The answer is -1 because a coefficient is the number in front of the variable which is -1 because there is an invisible 1 before the x
The y intercept is when x is 0. So, we have to plug in 0 for x. You can do this in many different ways as well.
7(0)-4y=8
-4y=8
Divide both sides by -4.
Y=-2
So, the Y intercept is -2 (0,-2).
