I bet you all are wondering: What is a linear equation????? YIP: a Linear Equation = an equation whose graph forms a straight line.

What is a Linear Equation? YIP: Linear equations are usually shown on a coordinate plane YIP: Real life situations of linear equations: the stock market the payments of a car Sports statistics

Example of a Linear Function Y 77 • (11,77) A Dog’s Human’s Equivalent Age Y = 7x 35 • (5,35) 21 • (3,21) X (0,0) 3 5 11 A Dog’s Actual Age

Let’s see if we can graph the line below… Example 1 Graph the line y = x + 1

YIP: Graphing using a Table of Values 1. Draw a table 2. Choose at least 5 inputs (x values) – some negative and some positive x rule: y = x + 1 y Notice I chose 1 negative, 0 and 1 positive input 1.3.1: Creating and Graphing Linear Equations in Two Variables

3. Substitute the inputs into the equation to find the outputs or y-values x Y = x + 1 y

4. Draw a coordinate plane. Be sure to label the x and y axis and write in an appropriate scale. 5. Plot the points and connect. y x
