Okay. Do you know how to find slope?

2. KierseyClemons

no

3. Dido525

Okay: $slope=\frac{ y2-y1 }{ x2-x1 }$

4. Dido525

We are given two sets of points. So we can use this formula. Do you understand?

5. KierseyClemons

yes thank you

6. Dido525

Wait. Remember that perpendicular slope is just the negative reciprocal of your slope.
