Graph two or more linear inequalities on the same set of coordinate axes. The inequality has been maintained. On this number line, points B and A are our original values of 2 and 5.

We can designate one pair of coordinates by x1, y1 read "x sub one, y sub one"associated with a point P1, and a second pair of coordinates by x2, y2associated with a second point P2, as shown in Figure 7.

Note that it is very important to say what x and y represent. Compare your solution with the one obtained in the example. No matter how far these lines are extended, they will never intersect. We will use 0, 1.

Ordered pairs of numbers are used to designate points on a plane. On this number line, points B and A are our original values of 2 and 5. We could choose any values at all. Remember, there are infinitely many ordered pairs that would satisfy the equation. Again, in this table wc arbitrarily selected the values of x to be - 2, 0, and 5.

Once it checks it is then definitely the solution. We could also say that the change in x is 4 and the change in y is - 1. Again, you could also have started with arbitrary values of y. A graph is a pictorial representation of numbered facts.

A linear inequality graphs as a portion of the plane. These are numbered in a counterclockwise direction starting at the upper right. We then shade this half-plane. Such equations are said to be in standard form. These values are arbitrary.

Why do we need to check only one point? Look at both equations and see if either of them has a variable with a coefficient of one. The line indicates that all points on the line satisfy the equation, as well as the points from the table. In this example we will allow x to take on the values -3, -2, -1,0, 1,2,3.

Step 2 Adding the equations, we obtain Step 3 Solving for y yields Step 4 Using the first equation in the original system to find the value of the other unknown gives Step 5 Check to see that the ordered pair - 1,3 is a solution of the system.

Note that the point of intersection appears to be 3,4. Again, you could also have started with arbitrary values of y. Since that point was above our line, it should be shaded, which verifies our solution. Instead of saying "the first term is positive," we sometimes say "the leading coefficient is positive.

Again, in this table wc arbitrarily selected the values of x to be - 2, 0, and 5. What is the solution set?Solve an Inequality - powered by WebMath.
