Solving systems of linear
inequalities
• Be sure y> -x + 2 and y s 3x + 4 are graphed.
Consider the point (0, 0)
A. Does (0,0) lie in the shaded region of y> -x + 2?
B. Substitute 0 for x and 0 for y in the inequality y > -x + 2,
and simplify. Show your work in the space to the right.

Is the inequality true?
C. Does (0,0) lie in the shaded region of y> -x + 2?
D. Substitute 0 for x and 0 for y in the inequality y > -x + 2,
and simplify. Show your work in the space to the right.
Is the inequality true?
E. Turn on Show solution test and check that the green point
is at (0,0). Is (0,0) a solution to the system of inequalities?
