Write the equation of the line in slope-intercept form that passes through the points (1, -1) and (3, 17).

y=9x-10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(17-(-1))/(3-1)

m=(17+1)/2

m=18/2

m=9

y-y1=m(x-x1)

y-(-1)=9(x-1)

y+1=9x-9

y=9x-9-1

y=9x-10

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
