Thank you for the opportunity to help you with your question!

slope  = change in y / change in x

Slope of Line 1

change in y = 37 - (-14) = 37 + 14 = 51

change in x = 11 - (-6) = 11 + 6 = 17

slope of line 1 = 51/17 = 3

slope of line 2

change in y = 12 - 11 = 1

change in x = -6 - (-3) = -6 + 3 = -3

Slope of line 2 = -(1/3)

L1 is perpendicular to L2


Please let me know if you need any clarification. I'm always happy to answer your questions.
