# Write an inequality for the graph weegy questions

To solve a system of two linear equations by graphing 1. These values of x give integers for values of y. This means the graphs of all systems in this chapter will intersect in a single point. If so, we shade the half-plane containing the test point; otherwise, we shade the other half-plane.

The number lines are called axes. If we add the equations as they are, we will not eliminate an unknown. 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.

The slope and y-intercept can be obtained directly from an equation in this form. If we write the slope asthen from the point 0,4 we move one unit in the positive direction parallel to the x-axis and then move three units in the negative direction parallel to the y-axis.

We now locate the ordered pairs -3,9-2,7-1,50,31,12,-13,-3 on the coordinate plane and connect them with a line. The value of m is 6, therefore the slope is 6. Locate these points on the Cartesian coordinate system.

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.

Step 5 Check the solution in both equations. In later algebra courses, methods of recognizing inconsistent and dependent equations will be learned. Solution We reason in this manner: Thus we multiply each term of this equation by - 1.

If you choose to eliminate y, multiply the first equation by - 2 and the second equation by 3. Since the line passes through the origin, we must choose another point not on the line as our test point. The line indicates that all points on the line satisfy the equation, as well as the points from the table.

To solve a system of two linear equations by graphing, graph the equations carefully on the same coordinate system. The next section will give us an easier method. If we denote any other point on the line as P x, y See Figure 7.

The intersection of the two solution sets is that region of the plane in which the two screens intersect. Find the equation of the line. The point 0,0 is not in the solution set, therefore the half-plane containing 0,0 is not the solution set. The first number of the ordered pair always refers to the horizontal direction and the second number always refers to the vertical direction.

Step 3 Solve for the unknown.

The ordered pair 5,7 is not the same as the ordered pair 7,5. A solution of an inequality in two variables is an ordered pair of numbers that, when substituted into the inequality, makes the inequality a true statement.Yes we have two inequalities, because 3 2 = 9 AND (−3) 2 = 9 Add 4 to both sides of each inequality: 1 ≤ W ≤ 7 So the width must be between 1.

What compound inequality represents the phrase? Graph the solutions. all real numbers that are greater than –8 and less than 8 - /5(11).

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.

Inequality Grapher Inequalities Solving Inequalities Solving Inequality Word Questions Algebra Index. It contains the symbols, ≤, or ≥. To write an inequality, look for the following phrases to determine where to place the inequality symbol. Key Vocabulary inequality, p.

solution of an inequality, p. solution set, p. graph of an inequality, p. EXAMPLE 1 Writing Inequalities Write the word sentence as an inequality.

a. In general, to graph a first-degree inequality in two variables of the form Ax + By = C or Ax + By = C, we first graph the equation Ax + By = C and then determine which half-plane (a region above or below the line) contains the solutions.

Write an inequality for a given sentence. Graph each inequality on a number line. State whether the inequality is true or false for the given value.
