Graph a straight line using its slope and y-intercept. Two-step inequalities. Solution 3x = 5 + 4y is not in standard form because one unknown is on the right. If you don't know how, you can find instructions. A linear inequality is an inequality which involves a linear function. To solve linear inequalities, isolate the variable on one side of the inequality, keeping track of the sign of the inequality when multiplying or dividing by a negative number, and express the solution as an interval. The numbers represented by x and y are called the coordinates of the point (x,y). We solve linear inequalities by separating (sometimes described as "isolating") the unknown variable from the rest of the inequality. We indicate the solution set of x + y > 5 with a screen to the right of the dashed line. Positive is to the right and up; negative is to the left and down. Example 10 Find the slope and y-intercept of 3x + 4y = 12. Examples of How to Solve and Graph Linear Inequalities. Thanks for the feedback. Example 2 Sketch the graph of 3x - 2y - 7.
