x - y - 3 = 0      This is a line...to graph it, pick some value for y, say 0.....then plugging this into the equation makes x = 3

So...we have one point on our graph, i.e.,  (3, 0)  ....now pick another value for y, say 1......then, putting this into the equation forces x to be 4....and we have a second point → (4, 1)

And two points are all we need to draw a graph of a line.......so, plot the points and connect them......your graph should look like something like this........https://www.desmos.com/calculator/4inleaswpp
