Answer:
y+6
Step-by-step explanation:
If we increase x then we need to do it with y by the same number.
We can not increase with different numbers.
Our rule of translation now is (x+6,y+6)
(x,y)=(x+6,y+6)
We have A(-6,2) then A'(0,8)
B(-5,5) then B'(1,11)

Answer: -4 (choice B)</h3>
==========================================================
Explanation:
The table says that when x = 1, the output is y = -2.
So the point (1, -2) is on the parabola.
The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.
Find the slope of the line through those two points. The slope here is the same as the average rate of change.
m = (y2 - y1)/(x2 - x1)
m = (-10 - (-2))/(3 - 1)
m = (-10 + 2)/(3 - 1)
m = -8/2
m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.
Let's simplify step-by-step.
