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.

Step-by-step explanation:
x = 2y
Table C represents the proportional relationship between the x and y values.
Step-by-step explanation:
Proportional relationship definition states that x increase y increases.Proportional relationship definition states that x decrease y decreases.Table A x decreases and y increases so it is not proportionate.Table B x decreases and y increases so it not proportionate.Table C x decreases y decreases and x increases y increase.Table C x remains 0 y to remains 0 so it is proportionate.Table D one part of x decreases and y increases it is not proportionate.Table C represents the proportional relationship between the x and y values.
Step-by-step explanation:
Proportional relationship definition states that x increase y increases.Proportional relationship definition states that x decrease y decreases.Table A x decreases and y increases so it is not proportionate.Table B x decreases and y increases so it not proportionate.Table C x decreases y decreases and x increases y increase.Table C x remains 0 y to remains 0 so it is proportionate.Table D one part of x decreases and y increases it is not proportionate.c Yes, it is a proportional relationship because the graph is a straight line (and passes the vertical line test)
Step-by-step explanation:
Table B shows a proportional relationship between x and y
Step-by-step explanation:
x y
1 0.5
2 1
7 3.5
8 4
It is clear from the table that y varies directly with x.
Using the formula
y ∝ x
y=kx
Where k is the constant of proportionality
In order to find 'k',
k=y/x
Putting the values of x and y from the given table to determine the constant of proportionality
For (1, 0.5)
k=0.5/1=0.5
For (2, 1)
k = 1/2 = 0.5
For (7, 3.5)
k = 3.5/7 = 0.5
For (8, 4)
k = 4/8 = 0.5
As the value of the constant of proportionality 'k' is the same.
Thus, table B shows a proportional relationship between x and y
