Answer:</h2>
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.

Now that we have the y-intercept, we can create the equation.

We can prove this by graphing both lines, like so.
I know, you have to divide 90 by what ever the length is, then you have to figure out where the points are. So it should be.... D!!!
6 + y × 9 (the x is a times sign btw)
