An automobile manufacturer claims that their van has a 40.3 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van. After testing 190 vans, they found a mean MPG of 51.4. Assume the population standard deviation is known to be 1.7. Required:
Is there sufficient evidence at the 0.05 level to support the testing firm's claim

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. : )
