It is an equation for a graph

This is a linear equation in slope-intercept form. m is the slope of the line and b is the y-intercept.

this is the slope-intercept of a linear graph. and it actually helps you graph easier.

The equation for slope intercept

y = mx+b is called the slope-intercept formula. The "m" is the slope, and the "b" is the y-intercept. When you are given two points and asked to find the equation in slope-intercept form, plug in the points you have into this equation to find out the equation containing the two points.
