Hi
graph
x<-4y-8
x+8 <-4y
(x+8)/-4 > y |dividing by negative number changes the direction of the Inequality
y < -x/4 - 2
I. Graph the line y = (-1/4)x - 2 | m=-(1/4) and y-intercept Pt(0,-2)
Plot y-intercept Pt(0,-2) and use slope to plot at least one more
for example Pt(4,-3). Connect with a line (dotted in this case as y is < )
Cannot demontrate that here.

II. Shade the region below the line
