Hello, this is a linear problem so we are working with y = mx + b
The problem tells us:
y = total cost
x = the megabytes of data that she used in a month
b = y-intercept, which is the initial value
The problem asks "Which part of the graph will represent the cost per megabyte of data used in each plan?"
It is asking for cost per megabyte... This is a rate. and m = slope = rate
So lets, reiterate.
y = total cost
x = the megabytes of data that she used in a month
b = y-intercept, which is the initial value
m = slope = rate = cost per megabyte of data used
Answer: The slopes of the two lines.
The third set is equivalent to
2x + y = 2
2x + y = -2
clearly inconsistent.

Answer:
first one
Step-by-step explanation:
yes, the interval does increase at -2. however, you can see it decreases again but starts rising up again at the interval 1.
