See below.

$4 x - 4 y \geq 28$ $4x-4y>=28$

Divide through by $4$ $4$ :

$x - y \geq 7$ $x-y>=7$

Consider the limiting case where $x - y = 7$ $x-y=7$

$:. y = x-7$

This is a straight line with a slope of 1 and a $y-$ intercept of $-7$

Hence, the solution set for our inequality is all points greater of equal to this line.

For which the graphic representation is the shaded area below:

graph{x-y>=7 [-22.8, 22.82, -11.4, 11.4]}

How do you graph the inequality 4x-4y>=284x−4y≥284x-4y>=28?
