Step 4 Find the value of the other unknown by substituting this value into one of the original equations. Since the point 0,0 is not in the solution set, the half-plane containing 0,0 is not in the set.

Step 2 Check one point that is obviously in a particular half-plane of that line to see if it is in the solution set of the inequality.

Mistakes can be located and corrected when the points found do not lie on a line. Note again that the solution does not include the lines. First locate the point 0, We thus refer to the third point as a "checkpoint. Step 4 Find the value of the other unknown by substituting this value into one of the original equations.

The graphical method is very useful, but it would not be practical if the solutions were fractions. Solution The solution set consists of all ordered pairs that make the statement true. As a check we substitute the ordered pair 3,4 in each equation to see if we get a true statement.

To obtain this form solve the given equation for y. Then solve the system. The number lines are called axes. These values are arbitrary.

The change in x is 1 and the change in y is 3. Compare your solution with the one obtained in the example. Observe that when two lines have the same slope, they are parallel.

These are numbered in a counterclockwise direction starting at the upper right. Study the diagram carefully as you note each of the following facts.

First we know that the solutions to an equation do not change if every term of that equation is multiplied by a nonzero number. The graphs of all first-degree equations in two variables will be straight lines. Step 2 Check one point that is obviously in a particular half-plane of that line to see if it is in the solution set of the inequality.

Independent equations The two lines intersect in a single point.

We must now check the point 3,4 in both equations to see that it is a solution to the system. Therefore, 3,4 is a solution to the system. In this section we will discuss the method of substitution. The first number of the ordered pair always refers to the horizontal direction and the second number always refers to the vertical direction.

Algebra 1 Solving Inequalities Review What inequality represents the verbal expression? What is the graph of the inequality? 6.

d inequality represents the graph? 8. 9. Write an inequality that describes this situation. Weegy: 7 (x+4+6y) = 7x + 28 + 42y User: Write an equation in point-slope form for the line through the given point with the given slope. (8, 3); m = 6 A.

y - 3 = 6(x + 8) B. y + 3 = 6(x - 8) C. y + 3 = 6x + 8 D. y - 3 = 6(x - 8) Weegy: b User: Find the slope of the line. Larry graphs the inequality mcjpg using the steps below. Step 1: Draw a number line, and place an open circle at Step 2: Shade to the left of -5 to represent less than Graphing Linear Inequalities.

This is a graph of a linear inequality: The inequality y ≤ x + 2. You can see the y = x + 2 line, and the shaded area is where y is less than or equal to x + 2.

The inequality already has "y" on the left and everything else on the right, so no need to rearrange. 2. Improve your math knowledge with free questions in "Write inequalities from graphs" and thousands of other math skills. How Do You Graph the Intersection of Two Inequalities?

Number lines help make graphing the intersection of two inequalities a breeze! This tutorial shows you how to graph two inequalities on the same number line and then find the intersection.
