Find the equation of the line perpendicular to y = - 2x + 3 that passes through the
point (4,9).

y=1/2x+7

Step-by-step explanation:

New slope is 1/2, so we need to plug in the coordinates to find b.

y=1/2x+b

9=1/2(4)+b

9=2+b

7=b

y=1/2x+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)
