3x y -4 2x 4y4 how to graph?

The first thing to do is to re-write the equation so it is comprehensible.

Then draw a table of 2 horizontal rows across the width of the notepad, label one line 'x' and the other one 'y' , and then draw 11 boxes for x -5 to x +5.

It should look like this:-

x -5 -4 -3 -2 -1 0 +1 +2 +3 +4 + 5

y

(I cannot draw the intervening vertical lines so you will have to imagine them.)

Calculate the figures for 'y' and draw up 'x' and 'y' axes scaled to fit.
