Answer:
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
