The format of 'the graph' depends on what you have been taught. I have shown two options.

Multiply everything by (-1) to make the #2x# positive. Note this action turns the inequality sign round the other way.

#+2x-5>=+10#

As 5 to both sides

#2x >=15#

Divide both sides by 2

#x>=15/2#

The filled in 'blob' means it #x# can take on that value
