In thisproblem
The solution is the shaded area below the dashed line y=kx
so
The inequality is of the form
y < Kx
Find out the equation of the dashed line
y=Kx
we ned only one point, because is a proportional relationship (the line passes throughtthe origin
we take the pint (1,2)
K=y/x=2/1=2
the equation of the line is y=2x
therefore
the inequality is
y < 2x
