Calculate the slope from 2 points. Y m x b. In slope-intercept form m is the slope and b is the y-intercept.
While you could plot several points by just plugging in values of x the point-slope form makes the whole process simpler.
Find the y intercept given two points. The equation point slope calculator will find an equation in either slope intercept form or point slope form when given a point and a slope. Calculate the slope from 2 points. Substitute x and y for one.
