Warm- up #38 Graph on the same coordinate plane: 1.) 5x +2y < -10 2.) y ≤ 2/3 x +4

F Solve by graphing: (0) (0) x y -5 -2 X

Solve by graphing: The area where shading overlaps

9.6 Graphing Systems of Linear Inequations Goal(s): To graph a system of linear inequalities in 2 variables

Steps to Graphing Systems of Inequalities Graph each inequality separately (Remember to make a dotted or solid line and shade) Shade in darker or with another color the section where the 2 shades overlap. The overlap is your solution.

Every point in the overlapping area will make both inequalities true. y = 2x + 0 Every point in the overlapping area will make both inequalities true.

x y 2 -3 x y 2

This graph represents which inequality? Check (0,0) Check “b” Check slope + or neg

This graph represents which inequality? Check (0,0) Check x and y intercepts Check dotted line

Solve by graphing: false true (0,0)?

(0,0)?
