Amath teacher gave her class two tests. twenty-five percent of the class passed both tests and 42 percent of the class passed only the first test. what percent of the students who passed the first test also passed the second?

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. : )

1. perpendicular

2. parallel

3. perpendicular
