Question

Graph the inequality x+5 grater than or equal to 0

Answer 1

The given inequality is

`x+5\ge0`

Consider the equation

`x+5=0`

`x=-5`

Mark the point (-5,0) on the graph and draw a vertical line.

we get the graph of the line x=-5.

The graph is

Now take the point (0,0) which does not lie on the line.

Substitute x=0 in the inequality, we get

`0+5\ge0`

`5\ge0`

It is true, so the point (0,0) lies in the given inequality. so shade the right side of the line.

The graph is
