What is the slope of the line through (-7,-2) and (-6, 7)? Choose 1
1
9
B
-9
9

Step-by-step explanation:

Slope is rise over run or change y/change x.

7 - -2 = 9

-6 - -7 = 1

Slope = 9/1 or 9

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
