A) there is a linear relationship with the test scores go up with increasing hours spent on hw
b) y=8x+40 so at x=3h, y=test score= 8*3+40 = 64
c) 40 represents test score when u spend 0 hour on hw
I believe it is 1x - 9y + 41
If you need an equation it is -3.4x=21.5
You simply divide both sides by -3.4 to get x=-6.32
if that's not right then just get on a calculator and calculate by doing what I said to divide
The shape has five edges (if your including the point at the top) and five faces
I think it might be f^-1 (x) = x/2 - 3/2
I hope this helps!
