Can someone please help me with I appreciate it thank you

c = 7.

Step-by-step explanation:

The slope = (y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the 2 points.

So here we have the equation

- 3 = (3 - (-3)) /(5 - c)

-3 = 6 / (5 - c)    Cross multiply:

-3(5 - c) = 6

-15 + 3c = 6

3c = 6 + 15

3c = 21

c = 7.

$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)
