I need help with this problem as there is no Y in the equation

2X-7=0

how would I plot that on a graph?

Thank you for your help!

it's just the vertical line x=7/2

Don't forget the axes, x=0, y=0. Not every line has both x and y in its formula.

All you need to do is plot two points, say, (7/2,0) and (7/2,1)

It doesn't matter what value y has, x=7/2. If you can find two points with 7/2 for the x-coordinate, just connect them to draw the line.
