I believe it is D because that is where they cross
Answer:
Q(-2,-7)

Step-by-step explanation:
We need to form a simultaneous equation and solve.
The point P has coordinates (1,8). Let the other point Q also have coordinate (x,y).
Then the average rate of change is the slope of the secant line connecting P(1,8) and Q(x,y) and this has a value of 5.
This point Q also lies on the given parabola whose equation is
Put equation (1) into (2) to get:
When x=-2, y=5(-2)-3=-7
Therefore the required point is Q(-2,-7)
Answer: x = 4 , y
=
0

i am not sure but tried .
Step-by-step explanation:
The formula is called the “midpoint formula”. It looks like this
m=(x1+x2)/2 , (y1+y2)/2 where m means midpoint. In your case it looks like this.
