Two quantities are related, as shown in the table: x y
2 3
4 4
6 5
8 6
Which equation best represents the relationship?
A. y = 1/2x + 2

B. y = 1/2x + 1

C. y = x + 2

D. y = 2x + 1

B. y = 1/2x + 1

Step-by-step explanation:

y is added up by 1, while it is split 1/2 from x.

hope this helps.

B. y = 1/2x + 1

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
