Which function is nonlinear?
A. y=3x+1/2
B. y=-x
C. y=2x(x=4)
D. y=1/2x-7

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

the ratio would be 4: 3, the four being for jackson, and the three being not for him.

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
