Solving Systems of Linear Inequalities 7/6/2015 Heading TSWBAT: solve a linear system of inequalities by graphing. Students solve a system of two linear equations in two variables algebraically and are able to interpret the answer graphically. Students are able to solve a system of two linear inequalities in two variables and to sketch the solution sets.

Notes 1.Write the equation in slope-intercept form. 2.Graph the y-intercept and slope. 3.Draw the line (solid or dashed). Dashed line Solid line Steps to Graphing Linear System Inequalities Above y-intercept Below y-intercept 4. Lightly shade above or below the y-intercept. 5. Graph the other equation. 6. Darkly shade overlap.

Summary To solve a system of ______ inequalities first put both equations into slope-________ form. Next find the m and b and plot your points. Make a _____/dashed line and then shade above/______ according to the sign. Do the same for the other equation. Now darkly ______ the overlap. linear intercept solid below shade
