I think It would be -4-(-8)/2-(-9)=-4+8/2+9=4/11 is the equation by using y2-y1/x2-X1
Sorry If I'm wrong.
So it would be 49+(20)+8
= 77
slope = change in y/ change in x
select two points on the line
(-4,4)
(0,1)
= (4-1)/(-4-0)
= -3/4
Answer:
The answer should be A. Y= -4x -9
So you foil out the problem and get
