Answer 1

Line B slope = 9

Explanation:

When dealing with perpendicular lines, we can let the slope we know represent m1, while the slope we don't know represents m2.

Thus, to find m2, we use the formula:

`m_(2)=(-1)/(m_(1) )`

If we plug in -1/9 for m1, we have:

`m_(2)=-(1)/((-1/9)) \\m_(2)=9`
