Question

Rebecca must complete 15 hours of volunteer work. She does 3 hours each day. Write a linear equation in slope-intercept form to represent the hours Rebecca still has to work after x days.

Answer 1

Answer:

y = 15 hour - 3 hours/day x days

y = 15 - 3x

y-intercept = 15 - 3(0)= 15 which is the amount of volunteer hours she must complete at day 0.

0 = 15 - 3x

3x = 15

x = 5 (Number of days she would have to volunteer)

Equation: y = 15- 3x
