State the slope and y-intercept of the line with equation y = 9 + 7x

slope: 7 (or 7/1)

y int: 9

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is y intercept

so in

y=9+7x

we can flip the numbers around

y=7x+9

so 7 is our slope and 9 is the y intercept

$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)

the discriminant is 64 + 4*1*12 = 112

this is prime.
