1. Objective - To graph linear equations using x-y charts. 1 2 4 5 7 2 2 One Variable Equations Two Variable Equations 2x - 3 = 11 +3 +3 2x = 14 x = 7 One Solution Two Solutions x + y = 5 Solutions: x = 1, y = 4 x = 2, y = 3 x = 4, y = 1 x = 5, y = 0 x = 7, y = -2 Ordered Pairs (x,y) (1,4) (2,3) (4,1) (5,0) (7,-2) x y 4 3 1 0 -2 Infinite Solutions
2. State whether the given point is a solution to 3x - y = 5. 1) (2, 1) 2) (4, 5) 3) (-3, -14) 4) 5) (-1, 2) 3(2) - 1 = 5 Yes 3(4) - 5 = 5 No 3( - 3) - - 14 = 5 Yes Yes 3(-1) - 2 = 5 No
3. Complete the chart and graph. y = 2x - 3 x y -3 -2 -1 0 1 2 3 2(-3) - 3 = -9 2(-2) - 3 = -7 -5 -3 -1 1 3 x y
4. Complete the chart and graph. y = 2x - 3 x y -3 -2 -1 0 1 2 3 2(-3) - 3 = -9 2(-2) - 3 = -7 -5 -3 -1 1 3 x y
5. Complete the chart and graph. y = 2x - 3 x y -3 -2 -1 0 1 2 3 2(-3) - 3 = -9 2(-2) - 3 = -7 -5 -3 -1 1 3 x y
6. Complete the chart and graph. y = 2x - 3 x y -3 -2 -1 0 1 2 3 2(-3) - 3 = -9 2(-2) - 3 = -7 -5 -3 -1 1 3 x y
7. Complete the chart and graph. y = 2x - 3 x y -3 -2 -1 0 1 2 3 2(-3) - 3 = -9 2(-2) - 3 = -7 -5 -3 -1 1 3 x y
8. Complete the chart and graph. y = 2x - 3 x y -3 -2 -1 0 1 2 3 2(-3) - 3 = -9 2(-2) - 3 = -7 -5 -3 -1 1 3 This line represents all real solutions to y = 2x - 3. x y
9. 1) 2x + y = 5 2) - x + 2y = - 4 - 2x - 2x y = - 2x + 5 + x + x 2y = x - 4 2 2 Solve the following equations for y. (Function Form)
