These equations are in the standard form (Ax + By = C [Note: A, B, C are all integers while A has to be positive]). To graph these equations, firsty you need to find the x and y intercept.
> X intercept: What 'x' equals when y is 0. In graphic terms, it's when the line is directly on the x-axis
> Y intercept: Essentially the same thing, but instead what y equal when x is 0. In graphic terms, it's when the line is directly on the y-axis.

For both equations, do these steps:
1. find the x-intercept by replacing y with 0. Then solve by isolating x by doing inverse operations to the right side of the equality symbol.
Example for one equation x - y = 2:
x - 0 = 2 ⇒ 2 + 0 = x
2 + 0 equals 2. X would be 2.
2. Check your work by inserting 2 for x in the original equation and see if it comes out true.
Example using x - y = 2:
2 - 0 = 2
2 subtracted by 0 equals 2? Yes. Therefore x = 2 is correct.
3. Plot it on the graph.
Example using x - y = 2:
Since y = 0 and x = 2, the ordered pair would be (2,0). Graph this by dotting or marking down (2,0).
4. Repeat all what you did for the x-intercept but this time solve for the y-intercept.
Example using x - y = 2:
In short, this will give you the ordered pair (0,-2).
5. Now draw a line through these points.
Example for x - y = 2 only:
