A psychologist designs an 8 - item pain survey asking athletes to identify their level of pain after a football injury. She is considering either a 5 - point scale or a 10-point scale. In how many different ways could a person answer each survey? Select all that apply

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

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. : )

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
