See below.

#4x-4y>=28#

Divide through by #4#:

#x-y>=7#

Consider the limiting case where #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]}
