Me identify the vertex & explain what method you used

(-2, 4)

Step-by-step explanation:

The given equation is already in vertex form: y = a(x - h)² + k    where

Therefore, y = (x - 2)² + 4    ⇒   (h, k) = (2, 4)

answer: options?

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
