Answer:

y=-4x+9

Explanation:

We will find an equation in the form of y = mx + b. We know m must be -4(because the slope must be the same for parallel lines), so we need to solve for b, which is the y-intercept. To do that, we will plug in the point C, giving us
5 = -4 * 1 + b. Adding 4 to both sides gives us b = 9, so that is the y-intercept.
