Unit 4 - Linear Equations EOC Review

Juan wants to rent a house. He gathers data on many similar houses. The distance from the center of the city, x, and the monthly rent for each house, y, are shown in the scatter plot. Juan models the data with a linear equation.

 Based on the scatter plot, what could the number 1275 represent in his equation?

• The estimated rent for a house in the center of the city

• The estimated minimum rent for a house far from the center of the city

• The estimated change in rent for each additional mile from the center of the city

• The estimated change in distance from the center of the city for each dollar in rent
