Answer:
R = -2
Step-by-step explanation
-9, -3 is the first point.
A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.
-9 - 7 = -2
-3 - 1 = -2 (r)
with a slope of 1/7, (-9, -3) connects to (-2, -2)

Answer:
Step-by-step explanation:
Let us assume that she makes 10 minutes of call.
Telecorp has a flat rate of 7 cents per minute. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.07 × 10 = $0.7
America's charges 25cents per call. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is $0.25
Phone busters charges 35 cents per call and 2 cents per min. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.35 + 10 × 0.02
= 0.35 + 0.2
= $0.55
The cheapest service is that of America's. Therefore, she should choose it.

Answer:
Terms: 4x, -
Coefficients: 4,
Step-by-step explanation:
The terms of an expression are the numbers and variables that are being added. In this expression 4x is being added to -. This means that they must be the terms. The coefficients are the constants that come before a variable. A variable is an unknown number represented by a letter, in this case, x. So the coefficients are 4 and because both these numbers are being multiplied by a variable.
