Step-by-step explanation:
-5 + 3 = -2
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
that is the sum of the interior angles of a triangle,or the 3 sided polygons
(-7,2)(4,6)
slope = (y2 - y1) / (x2 - x1)
slope = (6 - 2) / (4 - (-7) = 4 / (4 + 7) = 4/11
