4.7 Solving linear inequalities (EMA3H) A linear inequality is similar to a linear equation in that the largest exponent of a variable is 1. The following are examples of linear inequalities. 2 x + 2 ≤ 1 2 − x 3 x + 1 ≥ 2 4 3 x − 6 < 7 x + 2. The methods used to solve linear inequalities are similar to those used to solve linear equations. Graph the inequality. y < x. Solution: Replace the inequality symbol with an equal sign and graph the related equation. y = x. Plot two points to determine the line. We can plot the points (0, 0) and (1, 1) Since the inequality symbol is <, draw a solid line to show that points on the line are solutions of the inequality. Like linear equations, you can solve a linear inequality by using algebra to isolate the variable. Inequalities, however, have a few special rules that you need to pay close attention to. Inequalities, however, have a few special rules that you need to pay close attention to. 2. Solving Linear Inequalities. The procedure for solving linear inequalities in one variable is similar to solving basic equations. (See Solving Equations .) We need to be careful about the sense of the equality when multiplying or dividing by negative numbers. Following are several examples of solving equations involving inequalities.

The linear inequality and equality parameters are for dividing up the parameter space into permitted and forbidden regions through linear geometries, such as requiring that x(1) <= -2*x(2) + 5 which describes a straight line.

The steps for solving two variable linear inequalities are very similar. Let's try. a couple examples. (1) Graph the region of the linear inequality. Looking at this inequality, we should notice a number of things. It is in Slope-Intercept. form ( y = mx+b ), which means we can identify the slope and y-intercept of.
