    umm..usually by graphing it :) and finding the points of intersection. It is the most unreliable way to get a good answer tho, but it gives you an idea on what a solution means.

    I can see that your equations are perpendicular lines that cross....

    5x -9y = -54 -5x +9y = 54 <- if we multiply this by -1 we get: -1(5x -9y = -54) we are back to your same equation

    the answer is either all points are solutions or no points :)

    I agree. There are integer solutions: x=9n, y=5n+6, and \[n \in \mathbb{Z}\]

    before yo graphng it you have to change it to y inetersept form then make a atable of values then you get your corrdintaes together then you graph
