A cleaning company charges an equipment fee and an hourly fee. The total fee charged by the

company (in $) is given by the linear equation ? = ?? + ????. Answer the following questions:

  1. (2 pts.) What are the dependent and independent variables of the linear equation?

  2. (3 pts.) The y-intercept of the linear equation is 50 and the slope is 100. Explain, in two or three sentences, what this y-intercept and this slope represent.

  3. (3 pts.) What is the total fee charged by the cleaning company for 5 hours of work?

  4. (2 pts.) Is the correlation between the total fee of the cleaning company and the number of hours worked positive or negative?

The equation for a straight line between two variables, xx and yy, is y=mx+by=mx+b. In this equation, mm is the slope of the line and bb is the yy-intercept (the point at which the straight line crosses the yy-axis). When m<0m<0, the line has a negative slope. When m>0m>0, the line has a positive slope. The correlation coefficient, rr, can be used to calculate the values of mm and bb in a linear regression. First, use the values you have...
