5x + 4y = 9 If y=-4,X= 25/5 If y=-3,X= 21/5 If y=-2,X= 17/5 If y=-1,X= 13/5 If y=0, X= 9/5 If y=1, X= 5/5 If y=2, X= 1/5
X can be anything, depending on the Y value. Every time Y changes by 1 unit, X changes by 0.8 units. 5x + 4y = 9 Y=3, X=-3/5 Y=2, X=1/5 Y=1, X=5/5 It is a line with a gradient of 5/4 or 1.25
