Inequalities and graphs example 1
Graph the following inequality.
Subtract `x` from both sides to get `y` on its own.
Divide both sides by 2 to get `y` on its own.
First, let's calculate some points on the graph.
Now draw a graph and mark on the above points and don't forget to use just a dotted line.
Now pick a point NOT on the line:
Choose `x=0` and `y=3`
This reads 3 is greater than 4 which is of course incorrect.
So this DOES NOT SATISFY THE INEQUALITY.
DON’T SHADE IT.
Do shade the other side.
