Question

How do you graph the inequality `y <= 4x - 1`?

Answer 1

Graph and solve the inequality `y <= 4x - 1`

Explanation:

`y <= 4x - 1` (1).
First, graph the Line y = 4x - 1 (2) by its intercepts.
To find y-intercept, make x = 0 --> y = -1.
To find x-intercept, make y = 0 --> 4x = 1 --> `x = 1/4.`
Join these 2 intercepts to get Line (2).
The solution set of inequality (1) is the area below this Line (2). Color or shade this area, it is the answer.
Note: The Line (2) is included in the solution set.
