Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180 degrees, and each side of a straight line is equal to 180 degrees. Therefore, the exterior angle labelled 
must be equal to the sum of the two angles marked

Hello from MrBillDoesMath!
Answer:
Slope = 1/2
Discussion:
The slope of the line is given by
(change in y)/(change in x) =
(9-4)/( 8 - (-2) )
=
5/(8+2) =
5/10 =
1/2
Thank you,
MrB
