Answer:
Plug x-7 in for y, in the bottom equation.
x - 7 = 2 + 2x - 4
x - 7 = 2x - 2
x = 2x + 5
-x = 5
x = -5
Assume your line starts at zero, your first point is (-3,5) meaning your have a slope of 5/-3
[ f(x) = 5/-3x + b]
6+(9-1)^2/4 = 22
______________[
-1 - 10n is a simple version
The answer is 4 bc 4a+8b+4c=1. 4a*4=16a 8b*4=32b and 4c*4=16c so 1*4=4. since ur finding four times as much of the first problem then 16a+16c+32b=4
