Which equation represents a proportional relationship?

y=14x

y = 3x + 7

y=13x+1

14x+y=10

First option.

Step-by-step explanation:

The equation of a line that passes through the origin (which is the point ), has the following form:

Where "m" is the slope of the line.

By definition, Proportional relationships have this form:

Where "k" is the  Constant of proportionality.

Therefore, the graph of  a Proportional relationship is a straight line that passes through the origin; then:

Observe the equations provided in the exercise's options.

In this case you can identify that the only equation that has the form explained before, is the first one:

And the Constant of proportionality is:

add 5 subtract 1

step-by-step explanation:

answer is : muchas/tipicas

have a nice day!
