Amath club took a math test. twelve of the members had an average score of 80. eighteen of the members had an average score of 86. what is was the class average

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

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. : )
