Answer:
42
Step-by-step explanation:
Given m and n are parallel:
x + 138 = 180 because these angles are supplementary
subtract 138 from both sides
x = 42
Yes, you are correct, the answer is y = 20x + 40. 40 is the y-intercept value and 20 is the slope because that is the fee that must be payed every month, or x amount of times.
Let x = 0.
y = f(2*0)
y = 0
One point is (0, 0).
The answer is 200 because 100 plus 100 equals 200
