Hope this helped!
(2,5) and (4,13)
y - y1 = y2 - y1
x - x1 x2 - x1
y - 5 = 13 - 5 = 8/2 = 4 x - 2 4 - 2
y - 5 = 4x - 8
y = 4x - 3
m = 4, c = -3
I think the answer is yes
For x values 1 unit either side of the vertex, the value of y is 2 more than it is at the vertex.
a = 2

More formally, The graph appears to go through the point (4, 1). Substituting these values for (x, y) in the equation, we get
1 = a(4-3)² -1 . . . . substitute for x and y
2 = a . . . . . . . . . . add 1 and simplify
