Answer:

The correct option is C

The equation is:


y=-5x-2

Step-by-step explanation:

Given the equation:


y=-5x-5

Where the slope is -5 and y-intercept is -5.

An equation parallel to this have the same slope but different y-intercept. It is of the form:


y=-5x+b

Given that it passes through (-1, 3), we have:


\begin{gathered} 3=-5(-1)+b \\ 3-5=b \\ b=-2 \end{gathered}

The equation is therefore:


y=-5x-2
