Graphing inequalities in 2 variables
WebIf the inequality is < or > (with no equal to), the line is dashed. If the inequality is <= or >= (contains equal to), the line is solid. If the inequality is < or <=, shade below the line. If the inequality is > or >=, shade above the line. 4 comments ( 5 votes) Bleeblah101 10 years ago how do you know if you shade above or below? • ( 4 votes) WebSimilarly, linear inequalities in two variables have many solutions. Any ordered pair that makes an inequality true when we substitute in the values is a solution to a linear inequality. Solution to a Linear Inequality. An ordered pair is a solution to a linear inequality if the inequality is true when we substitute the values of x and y.
