Question

which equation has a constant of proportionality equal to 0.25?Choose 1 answer A.) y= 25x B.) y= 5/2x C.) y= 1/4xD.) y= 1/25x

Answer 1

Given data:

The first expression is y=25x.

The second expression is y=5/2 x.

The third expression is y=1/4 x.

The fourth expression is y=1/25 x.

The second expression can be written as,

y=2.5x

The third expression can be written as,

y=0.25x

so, in the above expression y is proportional to x, and constant of proportionality is 0.25.

Thus, C) option is correct.
