Solution The solution set consists of all ordered pairs that make the statement true. Check each one to determine how they are located. Check in both equations. Solve the system by substitution.

We then find the values for y by using the equation.

Our change in y is equal to negative 1. No matter how far these lines are extended, they will never intersect. Again, use either a table of values or the slope-intercept form of the equation to graph the lines.

A system of two linear inequalities consists of linear inequalities for which we wish to find a simultaneous solution. The change in x is 1 and the change in y is 3. You could have said, hey, what happens if I go back 4 in x? Thus we multiply each term of this equation by - 1. Remember, first remove parentheses.

Which graph would be steeper: We can figure out its y-intercept just by looking at it. Neither unknown will be easier than the other, so choose to eliminate either x or y. Replace the inequality symbol with an equal sign and graph the resulting line.

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. Always remember that inequalities do not have just one solution.

Again, compare the coefficients of x in the two equations. So if you think about this line, if you think about its equation as being of the form y is equal to mx plus b in slope-intercept form, we figured out b is equal to negative 2.

No, -3 is greater than -5, so in order to make it a true statement, we must reverse the sign. The stocks were not worth the same amount in the beginning, so if each stock loses half its value, the new values will not be equal either.

A linear equation graphs a straight line. A system of two linear equations consists of linear equations for which we wish to find a simultaneous solution.

Remember, x is written first in the ordered pair. Solution First we recognize that the equation is not in the slope-intercept form needed to answer the questions asked.

Instead of saying "the first term is positive," we sometimes say "the leading coefficient is positive. Here we selected values for x to be 2, 4, and 6. 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.Write an inequality for the graph shown below.

Use for your variable. 3. Write an inequality for the graph shown below. Use for your variable. 8. Final Exam Review (GInequalities) #2 Answers for class Basic Math / FND M FA 14 – N30FDNap 1. 2. 3.

Write an inequality for the graph shown below. Use x for your variable. Get the answers you need, now!5/5(1). If you want to impress your friends, you can write where the Greek letter (delta) Use the y-intercept and the slope to draw the graph, as shown in example 8.

This gives us a convenient method for graphing linear inequalities. To graph a linear inequality 1. Replace the inequality symbol with an equal sign and graph the resulting line. Solving Inequalities in One Variable.

When you graph inequalities that have only one variable, we use a number line. We will use open and closed circles and arrows pointing to the left or right to graph our answers. The next example is similar to example 1, but I would like to show you how to reverse your answer to make it easier to.

Write an inequality that represnts the graph below. use x as your variable. - Use interval notation to describe sets of numbers as intersections and unions. When two inequalities are joined by the word and, the solution of the compound inequality occurs when both inequalities are true at the same time.

It is the overlap, or intersection, of the solutions for each inequality.
