Work out m and c for the like: y=x+9

We are given the equation of the line in slope-intercept form (y=mx+c)

Where

m is the slope

b (or c) is the y-intercept.

The slope of the given line is 1, and the y-intercept is 9.

$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)
