Question

Which graph shows a proportional relationship in which the value of y is one-half of the value of x?

Answer 1

Answer:

Given that y varies proportionally with x , with a constant of proportionality k=13 , find y when x=12 .

Write the equation of the proportional relationship.

The variable x varies proportionally with y with a constant of proportionality equal to 13 .

So,

Substitute the given x value.
