The cost of the phone contract will be mathematically given as
C = 45 + 13m
This is further explained below.
<h3>
What is the formula?</h3>
Generally, According to the information provided, the monthly cost of the fixed line rental is £45, and the price of calls made is £13, thus the monthly cost will be represented by the following:
C = 45 + (13 × m)
Therefore
C = 45 + 13m
As a result, the price of the phone contract will be equal to C = 45 plus 13m, where m is the number of months in the contract.

Answer:
Option A is correct answer.
Step-by-step explanation:
An equation is having two sides equal. It has an = sign in it.
So, Option A 2y+7 = 9 is an equation as it has = sign in it. So, it is correct option.
All other options do not have = sign in them so, they are not equations.
First, lets break up the equation into pieces.
The first variable is slope, in your case here, we have a slope of -3 or -3/1.
The other variable is the y-intercept, which is where place on the graph where you plot (0,X), in your case here we got (0,-4). That is the y-intercept.
to graph it you have to plot the y-intercept, and then identify the slope.
Here is an example.
