a bathtub is draining at a constant rate. after 2 minutes, it holds 28 gallons of water. 3 minutes later, it holds 7 gallons of water. write an equation that represents the number y of gallons of water in the tub after x minutes. please help i really need to submit it

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

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. : )
