## horsealot203 Group Title I need help finding the y intercept: David does landscaping for private homes and businesses. He charges \$40.00 to travel to the site and then \$40.00 per hour for his services. The equation y = 40 + 40x models the charge for his services y for any number of hours x. a. Graph the equation. Describe your graph. b. What is the slope of the line? What does the slope represent? c. What is the y-intercept of the line? What does the y-intercept represent? d. Julia paid David \$240.00 for his services. How many hours did David work one year ago one year ago

1. Trollface3

0,40

2. horsealot203

So would the slope be 40/1?

3. Trollface3

yep

4. horsealot203

And the slope represents the rate David charges, correct?

5. Trollface3

no 40x + 40 is what he charges

6. Trollface3

wait I think it does

7. horsealot203

Ok, then what does the slope represent? Is it the correlation between the number of hours he works and the amount he is paid?

8. Trollface3

yea

9. horsealot203

Ok. So what does the y intercept represent?
