Explain how to tell which side of the line to shade ?

You should always use a reference point such as (0,0) to determine which side of the line to shade. For example we have the equation y>2x-1 we then use the point (0,0) by substituting the point in the equation.

y>2x-1 > 0>2*0-1

we then solve and make sure the point satisfies the inequality.

0>2*0-1 > 0-1=-1 > 0>-1

We see that the point does satisfy the equation so we shade whatever side of the line that includes the point (0,0)

Hope this helps!
