Please help<br><br> In which table does y vary directly with x?
grigory [225]

Answer:

Table D

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

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

<u><em>Verify each case</em></u>

<em>Table A</em>

For x=1, y=3

Find the value of k

k=y/x -----> k=3/1=3

For x=2, y=9

Find the value of k

k=y/x -----> k=9/2=4.5

the values of k are different

therefore

The table A not represent a direct variation

<em>Table B</em>

For x=1, y=-5

Find the value of k

k=y/x -----> k=-5/1=-5

For x=2, y=5

Find the value of k

k=y/x -----> k=5/2=2.5

the values of k are different

therefore

The table B not represent a direct variation

<em>Table C</em>

For x=1, y=-18

Find the value of k

k=y/x -----> k=-18/1=-18

For x=2, y=-9

Find the value of k

k=y/x -----> k=-9/2=-4.5

the values of k are different

therefore

The table A not represent a direct variation

<em>Table D</em>

For x=1, y=4

Find the value of k

k=y/x -----> k=4/1=4

For x=2, y=8

Find the value of k

k=y/x -----> k=8/2=4

For x=3, y=12

Find the value of k

k=y/x -----> k=12/3=4

All the values of k are equal

therefore

The table D represent a direct variation or proportional relationship

The linear equation is y=4x
