Answer:
Step-by-step explanation:
The constant of proportionality is the slope of the line joining the two points
(70,40) and (49,28).
Recall the slope formula:
We substitute the point to get:
<u>Alternatively</u>:
A proportional relation is given by
where k is the constant of proportionality.
Using any point, we substitute and solve for k.
Fist convert the equation to vertex form
y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106
So the vertex is at (-7,-106)
