Systems of Equations and Inequalities In previous chapters we solved equations with one unknown or variable. We will now study methods of solving systems of equations consisting of two equations and two variables. Represent the Cartesian coordinate system and identify the origin and axes. Given an ordered pair, locate that point on the Cartesian coordinate system.

Given a point on the Cartesian coordinate system, state the ordered pair associated with it. We have already used the number line on which we have represented numbers as points on a line.

Note that this concept contains elements from two fields of mathematics, the line from geometry and the numbers from algebra. Rene Descartes devised a method of relating points on a plane to algebraic numbers. This scheme is called the Cartesian coordinate system for Descartes and is sometimes referred to as the rectangular coordinate system.

This system is composed of two number lines that are perpendicular at their zero points. Perpendicular means that two lines are at right angles to each other. Study the diagram carefully as you note each of the following facts.

The number lines are called axes.

Example 3 Graph the solution for the linear inequality 2x - y ≥ 4. Solution Step 1: First graph 2x - y = 4. Since the line graph for 2x - y = 4 does not go through the origin (0,0), check that point in . Fit an algebraic two-variable inequality to its appropriate graph.

Solve, Graph and Write Inequalities Make sure that you can draw a graph from an inequality and write an inequality when given a graph. Pay attention to open and closed circles.

The horizontal line is the x-axis and the vertical is the y-axis. The zero point at which they are perpendicular is called the origin. Positive is to the right and up; negative is to the left and down. The arrows indicate the number lines extend indefinitely.

Thus the plane extends indefinitely in all directions. The plane is divided into four parts called quadrants. These are numbered in a counterclockwise direction starting at the upper right. Points on the plane are designated by ordered pairs of numbers written in parentheses with a comma between them, such as 5,7.

This is called an ordered pair because the order in which the numbers are written is important. The ordered pair 5,7 is not the same as the ordered pair 7,5. Points are located on the plane in the following manner. First, start at the origin and count left or right the number of spaces designated by the first number of the ordered pair.

Second, from the point on the x-axis given by the first number count up or down the number of spaces designated by the second number of the ordered pair.

Ordered pairs are always written with x first and then y, x,y. The numbers represented by x and y are called the coordinates of the point x,y. The first number of the ordered pair always refers to the horizontal direction and the second number always refers to the vertical direction.

Check each one to determine how they are located.

What are the coordinates of the origin? Find several ordered pairs that make a given linear equation true. Locate these points on the Cartesian coordinate system.

Draw a straight line through those points that represent the graph of this equation. A graph is a pictorial representation of numbered facts.We can also graph inequalities on the number line. The following graph represents the inequality x≤2.

The dark line represents all the numbers that satisfy x≤2. If we pick any number on the dark line and plug it in for x, the inequality will be true. Write an inequality for the graph Download jpg.

This Write and Graph Inequalities: Temperature Video is suitable for 6th - 8th Grade. What temperature does water freeze?

Have your learners show in an inequality all the possible temperatures. The video demonstrates how to set up an inequality based on the situation given and how to graph it. This quiz and worksheet will help you assess your knowledge of writing equations with inequalities.

To pass the quiz you must be familiar with signs related to writing these equations and other. Write and graph a linear inequality that represents th situation. To start out, you have to write the inequality they are asking for. I'm assuming we can't spend any more than $48, but we don't have to spend all of $ If it costs $5 for every album (x) and $8 for every movie (y), than we'd write an inequality: App for Students.
