Steps to graph an inequality 1.Graph like normal (slope and y- intercept) 2.Line: Solid (≥, ≤) or Dashed (>, <)? 3.Test point: Shade the truth OR When inequality is written in slope-intercept form,, and ≥ shade above the line

Steps to graph a system of linear inequalities 1.Graph each individual inequality with shading 2.Solution is area shaded twice

Steps to graph a system of linear inequalities 1.Graph each individual inequality with shading 2.Solution is area shaded twice

Which car cost under $20,000 with tax? How can you determine the cost of driving 10,000 miles for a car? Which cars costs less than $2,000 to drive 10,000 miles?

3-3 System of Linear Inequalities Objective: I can graph two-variable inequalities

1. [Y = ] 2. [◄], [◄], [enter] until inequality is selected 3.> or ≥ 4.< or ≤ 5. [►], [►], Enter equation 6.Repeat for all inequalities 1.Graph each individual inequality with shading 2.Solution is area shaded the same # of times as inequalities. Solving a System of Inequalities: by graphing
