How do you graph #y <2x - 1#?

We should first find out the values for which #y=2x-1#

Explanation:

The values for which #y=2x-1# lie in a straight line, as follows:

graph{2x-1 [-10, 10, -5, 5]}

For the points on the line, the y-coordinate is exactly #2x-1#; for example, the points #(1, 1)#, and the points #(2, 3)# are on the line. (See the graph).

Hence, any point above the line will satisfy #y>2x-1#, and any point #y<2x-1# will be below the line.

The solution is the set of points on the graph below the line #y=2x-1#
