Slot Work YIP: Supplementary Angles =180° Complementary Angles = 90° Table of Contents Date 10-31-16 Target Graph Linear Functions 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 A Dog’s Human’s Equivalent 35 Age 21 (0,0) • (11,77) Y = 7x • (5,35) • (3,21) 3 5 11 A Dog’s Actual Age X Let’s see if we can graph the line below… Example 1 Graph the line y = x + 1 6 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 7 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 8 4. Draw a coordinate plane. Be sure to label the x and y axis and write in an appropriate scale. 5.
