3. For example… 1+X=5 1+5X=16 Y=2(3X+5)-4

4. Let’s Get Ready Write your problem out. It is important to copy the problem correctly. Y=2(3X+5)-4

5. 1 st Set of Ordered Pairs Plug a number in for x. solve the equation. Y=2(3X+5)-4 Y=2(3x0+5)-4 2(0+5)-4 2(5)-4 10-4 X=6 Xy 0 6

6. 2 nd Set of Ordered Pairs Y=2(3X+5)-4 Y=2(3x1+5)-4 2(3+5)-4 2(8)-4 16-4 Y=12 X y 0 6 1 12

7. 3 rd Set of Ordered Pairs Y=2(3X2+5)-4 Y=2(3x2+5)-4 2(11)-4 22-4 Y=18 X y 0 6 1 12 2 18

8. 4 th Set of Ordered Pairs Y=2(3X+5)-4 Y=2(3x3+5)-4 2(14)-4 28-4 y=24 0 6 1 12 2 18 X y 3 24
