You could do this a couple different ways.

1: put any number into y, and solve for x. plot that point on a graph. do the same for a different value of y, and solve for x. plot it. do a couple more just to make sure they're all on the same line. If one isn't, that's probably a math error.

2: convert the equation to y=mx+b form. in that case, the y intercept is found by setting x = 0. Similarly, you could find another point, and plot it with a different value of y, but since you already have the y intercept you can make a line using the slope (if that's easier). once you put it into y= mx+b form, use m as your slope. but check a new point from your equation against the graph to verify you got the slope right.

With linear equations, two points determine a line, but using more points will help you verify they're correct.
