A, B and E

Step-by-step explanation:

y = (1/2)x has the form y = kx, with k = 1/2, its constant of proportionality.

A) 6y = 3x

y = (3/6)x

y = (1/2)x

B) We have to find the  slope of the line. Using points (0,0) and (4, 2)

slope = (2 - 0)/(4 - 0) = 1/2

C) We have to find the  slope of the line. Using points (0,0) and (2, 4)

slope = (4 - 0)/(2 - 0) = 2

D) We have to find the  slope of the line. Using points (2,1) and (4, 3)

slope = (3 - 1)/(4 - 2) = 1

E) We have to find the  slope of the line. Using points (4,2) and (10, 5)

slope = (5 - 2)/(10 - 4) = 1/2

40% off the regular price is the correct answer.
