Which is an equation of the line containing the points (4, 10) and (6, 11) in standard form?
A. –x + 2y = 16

B. x + 2y = 24

C. x – 2y = –16

D. 2x – y = –2

Option C, x - 2y = -16

Step-by-step explanation:

Step 1:  Find the slope

Step 2:  Plug in into point-slope form

Step 3:  Solve for x

Step 3:  Put the variables on one side

Option C, x - 2y = -16

$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)
