Answer:
y=-3x+8
Step-by-step explanation:
Parallel lines on a graph must have the same slope AND different y-intercepts.
Therefore, the slope of the parallel line is also -3, but we need to find the y-intercept given the point (-1,5) so the line passes through it:
y=mx+b
y=-3x+b
5=-3(1)+b
5=-3+b
8=b
Therefore, the equation of the line would be y=-3x+8
