See a solution process below:

Explanation:

First, solve for y:

4y - 77 + color(red)(77) >= 23 + color(red)(77)

4y - 0 >= 100

4y >= 100

(4y)/color(red)(4) >= 100/color(red)(4)

(color(red)(cancel(color(black)(4)))y)/cancel(color(red)(4)) >= 25

y >= 25

This graph will be represented by a vertical line cross the y axis at 25 and will include the value of 25:

graph{y >= 25 + 0x [-100, 100, -50, 50]}
