Slopes of parallel lines are equal. So slope of line r = -8/9

Hello.

Parallel lines have the same slope.

If the given line has a slope of [tex]\displaystyle-\frac{8}{9}[/tex], then the line parallel to it has the same slope.

Thus, line r has a slope of [tex]\displaystyle-\frac{8}{9}[/tex].

I hope it helps.

Have a great day.
