One of the tables shows a proportional relationship. Graph the line representing the proportional relationship from this table i
Mkey [24]

Answer:

Table C

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Find the value of the constant of proportionality in each table

Table A

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-3 ------>k=-3/-1=3  

This table has different values of k

therefore

the table A does not represent a proportional relationship

Table B

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=3 ------>k=3/1=3  

This table has different values of k

therefore

the table B does not represent a proportional relationship

Table C

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=2 ------>k=2/1=2  

For x=2, y=4 ------>k=4/2=2  

This table has the same value of k

therefore

the table C  represent a proportional relationship

Table D

For x=-2, y=-4 ------>k=-4/-2=2  

For x=-1, y=-2 ------>k=-2/-1=2  

For x=1, y=2 ------>k=2/1=2  

For x=2, y=6 ------>k=6/2=3  

This table has different values of k

therefore

the table D does not represent a proportional relationship
