As you can see point-slope form is nothing too complicated. Finding the Equation of a Line Given a Point and a Slope 1 - Cool Math has free online cool math lessons cool math games and fun math activities. This is the equation of a line on a graph to solve this you must realise the equation can also be written as 1y1m1x-2.
The point slope form is defined that the difference in the y-axis coordinate between two points y - y 1 on a line is proportional to the difference in the x-axis coordinate points x - x 1 and the proportionality constant m is the point slope of the straight line.
Y 2x b. Created by Sal Khan. One way is using the slope-intercept formula y mx b. M change in y change in x 43 62 1 4.
