The amount of money spent at the gas station varies directly with the number of gallons purchased. when 11.5 gallons of gas were purchased the cost was $37.72. how much would 8 gallons of gas cost?

Step-by-step explanation: y = kx

37.72 = k(11.5)

k = 3.28

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

don't report but were is the digram
