Answer:
The slope is
Step-by-step explanation:
∵ The rule of the slope passing through 2 points is:
m =
∵ The points are (7 , 8) and (-7 , 1)
∴ m =
The external angle (53°) is half the difference of the intercepted arcs (y°, 180°), so we have
53 = (180 - y)/2
106 = 180 - y
y = 180 - 106
y = 74
The appropriate choice for the value of y is ...
74
