2 answers:
Answer :- An exterior angle is created by extending one side of a triangle.
Explanation:-
Let ABC a triangle with interior angles ∠A, ∠B and ∠C and one of its side AB is extended to a point P such that a new angle ∠ACP is formed outside the triangle ABC named as exterior angle of ABC.
⇒∠BCA and ∠ACP are supplementary angles.
Also the measure of exterior angle is equal to sum of the opposite interior angles of a triangle.

First let's find the slope
Slope formula:
Given the two coordinates:
(-4,-7) (3,2)
x1,y1 x2,y2
Plug these numbers into the formula
In this case the mistake that was made was that the student wrote the slope negative instead of positive
Final answer:
