Answer:
It is undefined
Step-by-step explanation:
The points both go in a vertical direction.
Infinity
Slope = y2 - y1/x2 - x1
Given
x1 = 9
y1 = -3
x2 = 9
y2 = -8
Therefore
Slope = -8 -(-3) /9 - 9
= -8 + 3 /9 - 9
= -5/0
= infinity
77° + 90° + x° = 180°
x° = 180° -77° -90°
x° = 13°
they pay $x*35.25
this is the answer
