ASAP help - The water level in Ty’s swimming pool has a maximum depth of 4 feet. After a day of swimming with friends, the water level in the pool drops 6 inches. Which of the following could best be used to determine d, the depth of the water in feet, after Ty and his friends went swimming? *Show work*

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. : )
