6.8 –Systems of Inequalities
• Just like systems of equations, but do the inequality part!
• Just like systems of equations, but do the inequality part!
Ex. 1 Solve each system of inequalities by graphing.
a. y > -2x + 4
y + 2 < x
• Just like systems of equations, but do the inequality part!
Ex. 1 Solve each system of inequalities by graphing.
a. y > -2x + 4
y + 2 < x
y > -2x + 4
