Question

Write an equation for a line that is parallel to y = -3x – 5 that goes through the point (-1, 8)

Answer 1

y = -3x +5

Explanation:

Parallel means that both slopes are the same.

This gives us y = -3x + C so far.

To find the y-intercept, we need to get x to 0.

Since we know the point (-1, 8), we can plug the number in into our equation

y = -3x + C.

8 = -3(-1) + C

8 = 3 + C

8 - 3 = C

5 = C or C = 5.

Now plug in C into our unsolved equation to get y = -3x +5.
