Answer:

The equation parallel to the given line is:


y=-4x+32

Step-by-step explanation:

Given the equation:


y=-4x+23

The slope is -4 and y-intercept is 23.

An equation parallel to the given equation must have the same slope but different y-intercept.

Let the equation be:


y=-4x+b

To find b, we use the given point that the line passes through, (6, 8).

With x = 6 and y = 8.

Doing that, we have:


\begin{gathered} 8=-4(6)+b \\ \\ 8=-24+b \\ \\ b=24+8=32 \end{gathered}

Using the value of b above, we have the parallel equation as:


y=-4x+32
