Plug in the slope and the coordinates of one point in the line. The slope and y-intercept calculator takes a linear equation and allows you to calculate the slope and y-intercept for the equation. M y 2 - y 1 x 2 - x 1 Substitute x 1 y1 0 -3 and x 2 y 2 1 4 m 4 3 1 - 0 m 70.
It was changed to y -1x 12 so it will look like y mx b slope intercept form.
First of all calculate the slope of a line with two points given. How to find slope. Y is y co-ordinate and x is x co-ordinate. We then subtract this value from y which is 12-7489 4511.
