Write the equation in point slope form and slope intercept form given the line goes through the following points (0,1) and (3,-8). show all work to receive full credit.

M = y2-y1 / x2-x1 is the slope formula . 
I'm going to give you advise . 
y - y1 = m ( x -x1)

simply plug in your numbers 
x1 y1        x2  y2
(0,1)   &   ( 3 , -8)

plug these into your formula. 
forget the normal y and x , let them be.
