The slope intercept formula is, y=m x + b where m is the slope where b is the y -intercept The slope is the change in y over the change in x. This is commonly known as the riserun. This is also shown as the ΔyΔx. If you have any 2 points on the line than you can also use the formula y2−y- 1x2−x1 The y-intercept is where the line touches or intersects the y-axis. If the x coordinate is zero you can find out what the y-intercept is.
