Use x - y = 2
y = x - 2
Straight line graph with gradient=1 and intercept - 2 on y-axis. Since it is an inequality, the line is a dashed line and shade the region below the dashed line

What's the problem? Can you plot x - y = 2, or x = 2 + y?
Make a table of x/y values for the equality:
x: -5, -4, -3, -2, -1, 0, +1, +2, +3, +4, +5, etc.
y: -7, -6, -5, -4, -3, -2, -1, 0, +1, +2, +3, etc.
Now try the same for y less than 2, or x = 1 + y
y: -6, -5, -4, -3, -2, -1, 0, +1, +2, +3, +4, etc.
If you plot the co-ordinates for the equality,
can you see which direction/side the inequality is on?

Make a list of possibilities for x and y. Then graph the coordinates.

well i dont know how to put a pic on here so just graph:
y > -x - 2
and then since its greater than the shaded part is ABOVE the DASHED line.
