If you want to retake any learning targets or application tests, make sure to complete them by 4:00pm on Friday, January 16. No preparation work required. You can retake as many times as needed for learning targets, but only one retake is allowed for application tests. The retake score is the one that will be kept. Get ready for linear inequalities!

Graphing Linear Inequalities Type of Line Where to Shade
How to Determine the Type of Line to Draw
Graph y > x - 2. 1. Graph the line y = x - 2. x 2. Since y >, shade above the line. y
Graph y < x - 2. 1. Graph the line y = x - 2. x 2. Since y <, shade below the line. y
Do you do anything different when the line is dotted rather than solid?
Graph y > x - 2. 1. Graph the line y = x - 2, but make the line dotted. x 2. Since y >, shade above the line. y
Graph y < x - 2. 1. Graph the line y = x - 2, but make the line dotted. x 2. Since y <, shade below the line. y
Graph y > -½x + 3 Type of line: Solid Dotted x y
Graph y > -½x + 3 Type of line: Solid Dotted x Shade ___ the line. y Above Below
Graph y > -½x + 3 Type of line: Solid Dotted x Shade ___ the line. y Above Below
Choose the correct inequality for the graph shown. A. y < 1/3 x + 2 B. y < 1/3 x + 2 x C. y > 1/3 x + 2 D. y > 1/3 x + 2 y
Graph x > -2 1. Draw a dotted vertical line at x = -2. x 2. Shade to the right of the line. y
