The points ( - 5,u) and ( - 3,9) fall on a line with a slope of 6. what is the value of u?

Slope = y2 - y1 = x2 - x1

6 = 9 - u/ -3 - -5

6 = 9 - u/ 2

12 = 9 - u

-u = 3

$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)
