Answer:
R = (-12, 22)
Step-by-step explanation:
Unfortunately it's not a straight line, so gonna need to put in some extra work. Basically think of it like breaking it into it's horizontal and vertical components then doubling them.
From Q to M you move 10 spaces to the left, so to go from M to R you will go another 10 to the left. Similarly, you start at -10 for the y value and go up 16 to 6, and you will need to go up another 16 to get to R.
So for x, 8 -10 = -2 then -2 - 10 = -12, so R's x value is -12
y we do the same thing. Gonna do it in one step though. -10 + 16 + 16 = 22
So R is (-12, 22)
Lets say two numbers are x and y
x+y=70-----------------------eq1
x=4y--------------------eq2
4y+y=70
5y=70
y=70/5
y=14
then x=4*14
x=56
F(-2)= -12
Explanation: 2(-2) = -4
-4 - 8 = -12
