EXAMPLE 2: SOLVING A SYSTEM BY GRAPHING Graphing by hand is not always an effective way to get the intersection. A better way is to use your calculator to graph and get the intersection.
THERE CAN ALSO BE SYSTEMS WITH MANY OR NO SOLUTIONS. MANY NONE

REMEMBER: if you do not show me or if you do not get credit, you owe me your break time after class!!!! Start on the homework assignment. HOMEWORK 1.Check if (2,-5) is a solution of: 7x + 4y = -6 6x + 5y = -11 2.Graph the system and estimate the solution. x + y = 1 x – 3y = 5 3.How many solutions? If one solution, estimate the solution. 7x + 5y = 10 y = 7x + 2 CLASSWORK WITH YOUR TABLE PARTNER
