start by just writing the equation for the line in slope intercept formula.
points: (-4,0) ; (4,2)
slope = (2-0)/(4+4) = 1/4
y-intercept, b = 1
(looked at graph)
equation line:
y = (1/4)x + 1
solid line is "equal to"
shaded area is below means y-values are "less than" the expression.
y <= (1/4)x + 1
