Question

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

Answer 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`
