Given :
The monthly rent for an 800 square foot office is $975.
For an 1100 square foot office, the rent is $1125.
To Find : Write and solve a linear equation to find the monthly rent for a 1500 square foot office.
Solution:
We will form the equation using two points equation formula


Formula : 
Substitute the values





So, a linear equation to find the monthly rent is
where x is the square feet and y is the monthly rent.
Now we are supposed to find the monthly rent for a 1500 square foot office.
Substitute x = 1500


Hence the monthly rent for a 1500 square foot office is $1325 .
