Objective: Students can graph a line! Agenda: -POD -Graphing on a Calc -Job 6A How Assessed: Job 6A – Due Tues No Calculator: Problem Solve….. Library Tutoring on Saturday Wabbitemu App Friend’s share Your idea????? www.awesomealgebra.org

Steps to Graphing 1. Make an x, y table Select any 3 numbers for the x value Plug in the values for x to get 3 y values 2. List the 3 coordinates 3. Plot the 3 coordinates & Draw line w/ arrows 4. Label line & axis

How to Graph a line on a Graphing Calculator Solve for y= Go to y= and type in calculator Hit 2nd , Table to copy/verify table Hit “Graph” to graph the line

Special Situations when Graphing 1. Dealing with Fractions – Selected numbers that the denominator can go into evenly Use graphing calculator and pick points that come out even 2. Graphing y = 3 Make table and have all values for y be a 3 Use graphing calc and copy table Graphing x = 5 Make table and have all values for x be a 5 Note: Can’t Use Calc to graph x = 5
