Okay. Do you know how to find slope?

2. KierseyClemons Group Title

no

3. Dido525 Group Title

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

4. Dido525 Group Title

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

5. KierseyClemons Group Title

yes thank you

6. Dido525 Group Title

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