Find the slope and the y-intercept of the line. This example is written in function notation, but is still linear. As shown above, you can still read off the slope and intercept from this way of writing it. We can get down to business and answer our question of what are the slope and y-intercept.
History[ edit ] Historically, equations of motion first appeared in classical mechanics to describe the motion of massive objectsa notable application was to celestial mechanics to predict the motion of the planets as if they orbit like clockwork this was how Neptune was predicted before its discoveryand also investigate the stability of the solar system.
It is important to observe that the huge body of work involving kinematics, dynamics and the mathematical models of the universe developed in baby steps — faltering, getting up and correcting itself — over three millennia and included contributions of both known names and others who have since faded from the annals of history.
In antiquity, notwithstanding the success of priestsastrologers and astronomers in predicting solar and lunar eclipsesthe solstices and the equinoxes of the Sun and the period of the Moonthere was nothing other than a set of algorithms to help them. Despite the great strides made in the development of geometry made by Ancient Greeks and surveys in Rome, we were to wait for another thousand years before the first equations of motion arrive.
The exposure of Europe to Arabic numerals and their ease in computations encouraged first the scholars to learn them and then the merchants and invigorated the spread of knowledge throughout Europe. By the 13th century the universities of Oxford and Paris had come up, and the scholars were now studying mathematics and philosophy with lesser worries about mundane chores of life—the fields were not as clearly demarcated as they are in the modern times.
Of these, compendia and redactions, such as those of Johannes Campanusof Euclid and Aristotle, confronted scholars with ideas about infinity and the ratio theory of elements as a means of expressing relations between various quantities involved with moving bodies.
These studies led to a new body of knowledge that is now known as physics.

Of these institutes Merton College sheltered a group of scholars devoted to natural science, mainly physics, astronomy and mathematics, of similar in stature to the intellectuals at the University of Paris.
Thomas Bradwardineone of those scholars, extended Aristotelian quantities such as distance and velocity, and assigned intensity and extension to them. Bradwardine suggested an exponential law involving force, resistance, distance, velocity and time. Nicholas Oresme further extended Bradwardine's arguments.
The Merton school proved that the quantity of motion of a body undergoing a uniformly accelerated motion is equal to the quantity of a uniform motion at the speed achieved halfway through the accelerated motion. For writers on kinematics before Galileosince small time intervals could not be measured, the affinity between time and motion was obscure.
They used time as a function of distance, and in free fall, greater velocity as a result of greater elevation.
Only Domingo de Sotoa Spanish theologian, in his commentary on Aristotle 's Physics published inafter defining "uniform difform" motion which is uniformly accelerated motion — the word velocity wasn't used — as proportional to time, declared correctly that this kind of motion was identifiable with freely falling bodies and projectiles, without his proving these propositions or suggesting a formula relating time, velocity and distance.
De Soto's comments are shockingly correct regarding the definitions of acceleration acceleration was a rate of change of motion velocity in time and the observation that during the violent motion of ascent acceleration would be negative.
Discourses such as these spread throughout Europe and definitely influenced Galileo and others, and helped in laying the foundation of kinematics.
He couldn't use the now-familiar mathematical reasoning. The relationships between speed, distance, time and acceleration was not known at the time.
Galileo was the first to show that the path of a projectile is a parabola. Galileo had an understanding of centrifugal force and gave a correct definition of momentum.
This emphasis of momentum as a fundamental quantity in dynamics is of prime importance. He measured momentum by the product of velocity and weight; mass is a later concept, developed by Huygens and Newton.
In the swinging of a simple pendulum, Galileo says in Discourses  that "every momentum acquired in the descent along an arc is equal to that which causes the same moving body to ascend through the same arc.In this section we will derive the vector and scalar equation of a plane.
We also show how to write the equation of a plane from three points that lie in the plane. I am designing an Ethernet application where I am required to form the packet payload at a rate of bits each clock.
However, each clock, from 1 to 4 of the bit words forming the bits will be valid. Write the Equation of a Line Parallel to a line and through a point. Video Demonstration. Algebra ; Geometry ; Trigonometry; Students are often asked to find the equation of a line that is parallel to another line and that passes through a point.
Substitute the given point (1,7) into the x 1 and y 1 values y − 7= 3(x − 1) X. A Time-line for the History of Mathematics (Many of the early dates are approximates) This work is under constant revision, so come back later.
Please report any errors to me at [email protected] This is the first tutorial in the "Livermore Computing Getting Started" workshop. It is intended to provide only a very quick overview of the extensive and broad topic of Parallel Computing, as a lead-in for the tutorials that follow it.
Example 5: Find an equation of the line that passes through the point (-2, 3) and is parallel to the line 4x + 4y = 8 Solution to Example 5: Let m 1 be the slope of the line whose equation is to be found and m 2 the slope of the given line. Rewrite the given equation in slope intercept form and find its slope.
4y = -4x + 8 Divide both sides by 4.
