all the students in a science class complete a 15-point extra-credit assignment to raise their test scores. The new test scores is 15 points more then the original score. Let x=original score let y=new score.

take it another

it would take 7/10 of an hour too fill the pool.

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. : )
