How do you graph 3x - y -2?

Answer 1

Answer 2

This is an expression. Equations can be graphed, not expressions. Let's assume that the equation was supposed to be 3x-y-2 = 0

First, re-arrange so that y is isolated: y = 3x-2

Then plug in x values

Ex, x=1, so y=3(1)-2=1

x=2, so y=3(2)-2=4

So you have two points, (1,1) and (2,4)

Plot them both and since this is a linear graph, you can draw a straight line between the two points, continuing throughout the entire graph.
