for this im not sure what the slope would be but i know to just plug the rest in after
AbdullahM
  • AbdullahM
The slopes of 2 perpendicular lines when multiplied would be -1.

so -1/4 * 4/1

Lets say the slope for the line they want us to find is 'y', then: \(\sf\Large \frac{-1}{4} \times y = -1\)

hmm

4/1
AbdullahM
  • AbdullahM
correct, so the slope if 4, because 4/1 = 4
