# Jamie owns a house painting service. For each house, she charges $70 plus$40 per hour of work. A linear equation that expresses the total amount of money Jamie earns per house is y=70+40x. What are the independent and dependent variables? What is the y-intercept and the slope? Select the correct answer below:   A. The independent variable (x) is the amount, in dollars, Jamie earns for a house. The dependent variable (y) is the amount of time Jamie paints a house.Jamie charges a one-time fee of $40 (this is when x=0), so the y-intercept is 40. Jamie earns$70 for each hour she works, so the slope is 70.   B. The independent variable (x) is the amount, in dollars, Jamie earns for a house. The dependent variable (y) is the amount of time Jamie paints a house.Jamie charges a one-time fee of $70 (this is when x=0), so the y-intercept is 70. Jamie earns$40 for each hour she works, so the slope is 40.   C. The independent variable (x) is the amount of time Jamie paints a house. The dependent variable (y) is the amount, in dollars, Jamie earns for a house.Jamie charges a one-time fee of $40 (this is when x=0), so the y-intercept is 40. Jamie earns$70 for each hour she works, so the slope is 70.   D. The independent variable (x) is the amount of time Jamie paints a house.

Question
Jamie owns a house painting service. For each house, she charges $70 plus$40 per hour of work. A linear equation that expresses the total amount of money Jamie earns per house is y=70+40x. What are the independent and dependent variables? What is the y-intercept and the slope?

A. The independent variable (x) is the amount, in dollars, Jamie earns for a house. The dependent variable (y) is the amount of time Jamie paints a house.

Jamie charges a one-time fee of $40 (this is when x=0), so the y-intercept is 40. Jamie earns$70 for each hour she works, so the slope is 70.

B. The independent variable (x) is the amount, in dollars, Jamie earns for a house. The dependent variable (y) is the amount of time Jamie paints a house.

Jamie charges a one-time fee of $70 (this is when x=0), so the y-intercept is 70. Jamie earns$40 for each hour she works, so the slope is 40.

C. The independent variable (x) is the amount of time Jamie paints a house. The dependent variable (y) is the amount, in dollars, Jamie earns for a house.

Jamie charges a one-time fee of $40 (this is when x=0), so the y-intercept is 40. Jamie earns$70 for each hour she works, so the slope is 70.

D. The independent variable (x) is the amount of time Jamie paints a house. The dependent variable (y) is the amount, in dollars, Jamie earns for a house.

Jamie charges a one-time fee of $70 (this is when x=0), so the y-intercept is 70. Jamie earns$40 for each hour she works, so the slope is 40.
