21. The Stanford-Binet IQ test with a normal distribution has a mean of 100 and a standard
deviation of 15. What would be the Standard Score (z-score) for an IQ of 140? (see formula
page)

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. : )
