    slope intercept form is y = mx + b where m is the slope and b is y-intercept right?

    \[m = \frac{y_2-y_1}{x_2-x_1}\] where points (x1, y1) and (x2, y2) are on the line

    \[m=\frac{ y _{2}-y _{1} }{x _{2}-x _{1} } \] or \[ m=\frac{ 20-4 }{4-0 }\]

    so (4, 20) and (0, 4) are the points can you find the slope with the formula

    so the slope is 4 and you put that in the equation
