**Objective The student will be able to:**

complete a table for a linear equation and graph the ordered pairs. Designed by Skip Tyler, Varina High School Modified by Johnny Kissko, Frenship High School

2
**List some pairs of numbers that will satisfy the equation x + y = 4.**

x = 1 and y = 3 x = 2 and y = 2 x = 4 and y = 0 What about negative numbers? If x = -1 then y = ? y = 5

3
**x + y = 4 What about decimals? If x = 2.6 then y = ?**

Now, let’s graph the pairs of numbers we have listed.

4
(1, 3) (2, 2) (4, 0) (-1, 5) (2.6, 1.4) • • • • • Connect the points on your graph. What does the graph look like?

5
**It is a straight line! It is a linear relation.**

• What does the line represent? • • • • All solutions for the equation x+y=4! Is (3, -1) a solution to this equation? NO! You can check by graphing it or plugging into the equation!

6
**1) Which is a solution to 2x – y = 5?**

(2, 1) (3, 2) (4, 3) (5, 4) Answer Now

7
**2) Which ordered pair is not a solution to the graph shown?**

(0, -1) (3, 5) (-2, -5) (-3, -1) Answer Now

8
**3) Solve the following equation for y: 2x + y = 4**

Draw “the river” Subtract 2x from both sides Simplify. Write the equation with the variable first. -2x x y = -2x + 4

9
**4) Solve the following equation for y: 4x - 5y = 7**

Draw “the river” Subtract 4x from both sides Simplify. Write the equation with the variable first. Divide both sides by -5 Does the fraction simplify? -4x x -5y = -4x + 7

10
**5) Solve the following equation for y: 6x – 2y = 8**

Answer Now

11
**6) Make a table and graph the solution set of 4x + 2y = 6.**

Draw “the river” Subtract 4x from both sides Simplify. Write the equation with the variable first. Divide both sides by 2 Does the fraction simplify? -4x x 2y = -4x + 6

12
**Let’s use the domain {0, 1, 2} for our equation.**

Create a t-table by picking at least three numbers to plug into our equation. Let’s use the domain {0, 1, 2} for our equation. x 1 2 ordered pair y -2(0) (0, 3) -2(1) (1, 1) -2(2) (2, -1)

13
**Draw a line through your points. It should be a straight line.**

Graph {(0, 3), (1, 1), (2, -1)} • • • Draw a line through your points. It should be a straight line.

14
Graph {(0, 3), (1, 1), (2, -1)} • • •

15
