**Bell Work 1/29/15**Solve the system by graphing.**Yesterday’s Homework**• Any questions? • Please pass your homework to the front. • Make sure the correct heading is on your paper. • Is your NAME on your paper? • Make sure the homework is 100% complete. • Incomplete work will NOT be accepted.**Heading**10/21/2019 Solving Systems by Graphing (not y = mx+b) TSWBAT: solve a linear system by graphing when not in slope-intercept form. Students solve a system of two linear equations in two variables algebraically and are able to interpret the answer graphically. Students are able to solve a system of two linear inequalities in two variables and to sketch the solution sets.**Notes**• Solving a System of Equations by Graphing 1. Write each equation into slope-intercept form. What is m and b? m = move b = beginning 2. Graph both equations in the same coordinate plane. 3. Find the point of intersection. 4. Check your answer. - Plug that point into both equations and make sure that it is true for both.**Notes**Now you try. Put in slope-intercept form. Ex. Ex. Ex.**Notes**Solve the system by graphing. Ex. 1) Put in slope-intercept form. 2) Graph the equations. - Find m and b first. 3) Point of intersection? 4) Check answer!**Notes**Now you try. Solve the system by graphing. Ex. 1) Put in slope-intercept form. 2) Graph the equations. - Find m and b first. 3) Point of intersection? 4) Check answer!**Notes**Solve the system by graphing.

Ex. 1) Put in slope-intercept form. 2) Graph the equations. - Find m and b first. 3) Point of intersection? 4) Check answer!**Summary**• To solve a linear system by ________ first put both equations in _____-_________ form. Then graph each equation separately. Next identify the ___________ of both lines and circle it. That ordered pair is the _______ to the system. • graphing • slope • intercept • intersection • solution**Today’s Homework**• Rules for Homework • Pencil ONLY. • Must show all of your work. • NO WORK = NO CREDIT • Must attempt EVERY problem. • Always check your answers.**Homework 6.1B**Solve the system by graphing.**Ticket Out the Door**• Complete the Ticket Out the Door without talking!!!!! • Talking = time after the bell! • Put your NAME on the paper. • When finished, turn your paper face DOWN. • Solve the system by graphing.
