Answer:
I believe the answer is C.
Step-by-step explanation:
The value of r in the given coordinates with their slope is; r = 7
How to find the Slope of a Line?
The formula for slope of a line passing through 2 points is;
m = (y2 - y1)/(x2 - x1)
We are given the coordinates as;
(1,-10) and (r,2)
The slope of the line passing through this coordinates is 2. Thus;
(2 + 10)/(r - 1) = 2
12 = 2r - 2
2r = 14
r = 14/2
r = 7

A) 4a+ ………………………. Plz thank me I need points lol
So just switch x and y to get:

and solve for x.
so f(-1) = x = 2y -10
