No, probably is on a scale between 0 and 1. Anything beyond those numbers is mathematically impossible. Since 3/2 = 1.5, it is not valid
The equation factored would be (x+7)(x-2). As 7-2=5 and (7)(2)=14.
Is there another part to your question
(-3,5). (2,-3)
x1,y1. x2,y2
y2-y1. -3-5. -8
--------- = ------- = ----- =8 =m
x2-x1. 2-3. -1
plug the rest in
