Question

Martha earns $15 per hour for babysitting. The parents always give her a $5 tip.

-What is the slope of this situation?
-What is the y-intercept in this situation?
-How many hours did Martha babysit if she made $65?
(Please help me)

Answer 1

The slope is: 15x
The y intercept is: 5
Which means the equation is y=15x+5 so the answer is 3

Answer 2

3

y=3x

4 hours

Explanation:

15 dollars in one hour plus 5 as tip makes the ratio afterwards 15\5 which equals 3. 65 dollars - 5 equals 60, which divided by 15 = 4 hours.
