Systems of Equations and Inequalities
... Solve Systems by Substitution • Think about parallel lines. If your two equations are parallel lines you will either have infinitely many solutions or no solutions. • Example: The sum of the measures of angles X and Y is 180 (They are supplementary). The measure of angle X is 24 greater than angle ...

The Slope-Intercept Formula
... Write in slope-intercept form then name the slope (m) and y-intercept (b). These are special equations. When you only see one variable, that means the line only touches one axis. ...

Evaluating algebraic expressions:
... The substitution method is used to eliminate one of the variables by replacement when solving a system of equations. 1. Solve one of the equations for either "x =" or "y =". This example solves the second equation for "y =". 3y - 2x = 11 y = 9 - 2x 2. Replace the "y" value in the first equation by w ...

Graphing Lines
... like a straight line. There are different methods to graph this type of equation. This handout will only present some of the most common. 1. Table of values– The most straight forward way to graph any equation is to make a table of x values versus y values, once a table is generated, the points are ...

Solving Systems of Linear Equations
... Multiply one or both equations by factors that will prove opposites coefficients for one of the variables, if needed. Add the equations to eliminate one equation and one variable. Solve the linear equation obtained in step 3. Do one of the following: A. Substitute the value obtained in step 4 into e ...
