NEED HELP RIGHT NOW. i have a math test and i dont know if this is a linear or non-linead relation!!!​

Non linear

Step-by-step explanation:

x is increasing steadily at a constant rate however the change in the y values vary from x values and they are not constant so this line is non linear

$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)
