7-6 Inequalities
Steps to Graphing Systems Solve both for y Graph the lines y = mx + b (dashed if < or >) Use a check point and shade in the correct direction Highlight the double shaded region.
First get both equations solved for y. Example y > 3x + 1 4x + 2y < -4 -4x -4x 2y < -4x – 4 ÷2 ÷2 y < -2x – 2 First get both equations solved for y.
Next, graph the 1st line and shade Example y > 3x + 1 y < -2x - 2 Next, graph the 1st line and shade
Example y > 3x + 1 y < -2x - 2
