A line passes through the point (3,1) and has a slope of 2.

what is the y-intercept?

-5

Step-by-step explanation:

First, we can plug all the given values into the equation y=mx+b. This is called slope-intercept form. m is the slope and b is the y-intercept. To find the y-intercept, we solve for b.

y=mx+b

1=2(3)+b

1=6+b

Subtract both sides by 6

1-6=6+b-6

-5=b

Therefore, the y-intercept is -5.

$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)
