Step by step
The question
Question: graph x > 2.
The answer is not one point.
It is every point that makes this true.
That is a whole part of the grid.
1 Draw the line
First we draw the line where both sides are equal: x = 2.
The sign is more than, with no "or equal to".
So points on the line are not answers.
We draw it dashed, like the open circle on a number line.
Draw the grid.
The x-axis goes across.
The y-axis goes up and down.
They meet at 0.
That point is called the origin.
x = 2 is a vertical line through 2 on the x-axis.
Straight up and down: dashed.
2 Test a point
The line cuts the grid in two sides.
One side is the answer.
We test one point: (0, 0).
Zeros are easy to work with.
Put x = 0 and y = 0 in.
Is 0 more than 2?
No, that is false.
So (0, 0) is not an answer.
3 Shade
So we shade the other side, away from (0, 0).
Every point there is an answer.
4 Check
Let's check with a point in the shaded part: (3, −1).
Put x = 3 and y = −1 in.
True!
So the shading is right.
Let's look back.
First: draw the line.
Then: test a point.
Then: shade.
Last: check.
