To sketch the graph of a line using its slope: To solve a system of two linear equations by graphing, graph the equations carefully on the same coordinate system. 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. Replace the inequality symbol with an equal sign and graph the resulting line. You will study these in future algebra courses. Hence, the solution is the other half-plane. Take a look at the following example: |3 x - 2| > 7. And since its greater than, draw a line going to the right.

The sight of a positive y> means it will be above the line, a positive y< means it will be below the line. Solve a compound inequality with "and." Step 1. Again, were going to treat it as a regular equation when solving . Independent equations The two lines intersect in a single point. Solve. Since the graph of a first-degree equation in two variables is a straight line, it is only necessary to have two points. Inequality represents an order relationship between two numbers or algebraic expressions, such as greater than, greater than, or equal to, less than, or less than or equal to. 4x < 20. When solving inequalities, it is usually easiest to collect the variables on the side where the coefficient of the variable is largest. Determine when a word problem can be solved using two unknowns.
