Alice owns a snow shoveling business. For each driveway, she charges $50 plus $70 per hour of work. A linear equation that expresses the total amount of money Alice earns per driveway is y=70x+50....

The independent variable (x) is the amount of time Alice shovels snow. The dependent variable (y) is the amount, in dollars, Alice earns for a driveway.


Alice charges a one-time fee of $50 (this is when x=0), so the y-intercept is 50. Alice earns $70 for each hour she works, so the slope is 70.
