So, we'd set up this equation like this: 
2x + 500 = 2800. 
500 would be our y-intercept, x is 1 month, 2800 is the total cost, and of course we have the 2 as a slope because it's 2 months rent. 
For the first step, subtract 500 on both sides. 
You should come up with 2x = 2300. 
To find the rent for just one month, which is x, divide both sides by 2. 
x = 1150. Therefore, the rent for one month is $1150.
