Answer:
D.
Step-by-step explanation:
in order to choose the correct answer, it is enough to substitute the given coordinates [(-3;-1) and (-6;8)] into the equations:
A. -1-8=3(-3+6); ⇔ -9≠9; wrong
B. -1+8=-3(-3+6); ⇔ 7≠-9; wrong
C. -1+8=3(-3-6); ⇔ 7≠-27; wrong
D. (-3;-1): -1-8=-3(-3+6); ⇔ -9=-9
(-6;8): 8-8=-3(-6+6); ⇔ 0=0 - correct.
Note, the suggested way is not the only one.
PS. the given points are (-3;-1) and (<u>-6;</u>8).
Since the total of exterior angles of a plane figure is always 360, you would divide 360 by 20 which gives you 18
