Answer: C. y=4x
Step-by-step explanation:
Proportional relationship means that the line will be going through the origin, meaning that if the x coordinate is 0, then y has to also equal to 0. Also another way to determine a proportional relationship is by identifying the slope and y intercept. If the line has a y-intercept then it is not proportional because it will not be going through the origin.
y = 4x Input 0 for x and y.
0 = 4(0)
0 = 0
This makes the statement true because if x is 0 then y is also 0.
