Ryan owns a snow shoveling business. For each driveway, he charges $50 plus $70 per hour of work. A linear equation that expresses the total amount of money Ryan earns per driveway is y=70x+50. What are the independent and dependent variables? What are the y-intercept and the slope?
Select the correct answer below:
The independent variable (x) is the amount of time Ryan shovels snow. The dependent variable (y) is the amount, in dollars, Ryan earns for a driveway.
Ryan charges a one-time fee of $50 (this is when x=0), so the y-intercept is 50. Ryan earns $70 for each hour he works, so the slope is 70.
The independent variable (x) is the amount of time Ryan shovels snow. The dependent variable (y) is the amount, in dollars, Ryan earns for a driveway.
Ryan charges a one-time fee of $70 (this is when x=0), so the y-intercept is 70. Ryan earns $50 for each hour he works, so the slope is 50.
The independent variable (x) is the amount, in dollars, Ryan earns for a driveway. The dependent variable (y) is the amount of time Ryan shovels snow.
Ryan charges a one-time fee of $50 (this is when x=0), so the y-intercept is 50. Ryan earns $70 for each hour he works, so the slope is 70.
