Answer: The equation is y = 3.25 + 7.5x and Todd bought 11 pictures
Step-by-step explanation:
f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Do you see the h and k in your equation?
-h = -(-2) = 2
We see that k = -4.
Our vertex is (2, -4).
..........................
b = - 4
slope m = (0 + 4)/(4 - 0) = 4/4 = 1
equation
y = x - 4
Answer = b. 7
