The graph of a proportional relation is a single, straight line in the coordinate plane that passes through the origin. We will check if x is proportional to y by drawing a line passing through the given points. Let's first plot the points as (x,y) coordinate pairs.
Now, let's connect these points with a straight line.
Since the line passes through the origin, x and y are proportional.
