Problem B
Looking at the graph
The solution is the shaded area below the solid line
the inequality is of the form
so
Find out the equation of the solid line
we need two points
(0,-3) and (1,0)
Find out the slope
m=(0+3)/(1-0)
m=3
we have
b=-3 (y-intercept)
substitute
y=3x-3
therefore
the inequality is
