Algebra 2 Graphing Linear Inequalities in Two Variables

Types of Graphs of Linear Inequalities in Two Variables The lines that are graphed will be either solid or dashed based on the inequality symbol: will be dashed lines ≤ or ≥ will be solid lines One side of the line will be shaded.

Questions that you need to answer when graphing linear equations in two variables 1.Will the line be solid or dashed? 2.Is the line in slope-intercept form? 3.What is the slope of the line? 4.What is the y-intercept of the line? 5.Where do you start when you graph? 6.How do you find another point on your line? 7.Which side do you shade on?

Answer: 1.Will the line be solid or dashed? Solid because ≥ 2.Is the line in slope-intercept form? yes 3.What is the slope of the line? m = -2/1 4.What is the y-intercept of the line? b = -2 5.Where do you start when you graph? (0, -2) 6.How do you find another point on your line? From (0, -2) move down 2 spaces and right one space 7.Which side do you shade on? ≥ means shade above your y-intercept
