7 is a prime number, which means it can't be simplified. This fraction is already in simplest form, also because 25 and 7 don't have any common factors.
The slope 1/2 y -intercept -2
If the volume of a cube is 27 it means that one edge is equal to the cube root of 27
3*3*3=27
Edge=3

V= 15 steps are down below
Slope = (-6 - 3)/(1+2) = -9/3=-3
y - 3 = -3(x +2)
y - 3 = -3x - 6
3x + y = -3
answer is 3x + y = -3 (third one)
