Answer:

Step-by-step explanation:

"y = 1 5 x" is ambiguous; please do not leave spaces. I'm assuming you meant y = 15x.

If you graph this, you'll see a line with slope 15 that goes through the origin. If there were a y-intercept other than zero, such as in y = 15x + 5, this equation would not represent a proportional relationship.

In summary:

There's a constant ("constant of proportionality") slope, which here is 15.

The line MUST go through the origin.

<h2>Answer:</h2>

When you graph the equation, you get a straight line that passes through the origin, which means the relationship is proportional. The constant of proportionality is the y-value when x = 1, which is 1/5.
