The true statements about Marcus graph are:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
<h3>How to determine the true statement</h3>
From the complete question, we have the following parameters:
<u>Phone service 1</u>
- Initial cost: $40
- Rate: $8.50 per service
<u>Phone service 2</u>
- Initial cost: $30
- Rate: $10.50 per service
By comparing the above parameters:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
The above statements represent the true statements about the Marcus' graph

Answer:
lower left
Step-by-step explanation:
We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.
x-coefficient : y-coefficient : constant
= 2 : 1 : -15 . . . . . in the given equation
2 : -2 : 30 = 1 : -1 : 15 . . . upper left — not the same
-4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same
-4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation
-4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same
Answer:
y=110 because the angles correspond
x=55 because they are verticals angles and are congruent so you set them equal to each other
Explanation:
2x=110
x=55
