PLEASE HELP ME!

At the beginning of the summer, Paul has $76. During the summer, he earns money by mowing lawns. The table shows the total amount of money Paul has after mowing the given number of lawns.

Select from the drop-down menus to make an equation in slope-intercept form that gives the total amount of money, y, Paul has after mowing x lawns.

y = x =

76 12

24 24

12 76

10 100

Answer 1

at the beining, he has 76
that is at x=0
y=mx+76

find m
given
when x=2, y=100
find m

100=2m+76
minus 76 both sides
24=2m
divide both sides by 2
12=m

the equatin is

y=12x+76
