1. Bell Work Solve. 1. 5 = a – 2 2. 7 + n = 24 a = 7 n = 17
3. 3c – 7 = 32
4. 17y + 7 = 58
c = 13
y = 3

2. Learning Target:
I can
Determine if an ordered pair is a solution to an equation
Create a table of Ordered Pair Solutions

3. a value for the variable that makes an equation true
Vocabulary
- an (x, y) point
ordered pair
a math sentence
it has an = sign
equation
solution
a value for the variable
that makes an equation true

4. Do this one along with me:
Determine whether each ordered pair is a solution of y = 4x – 1.
(3, 11)‏
y = 4x – 1
11 = 4(3) – 1 ?
Substitute 3 for x and 11 for y.
Simplify.
11 = 11 
(3, 11) is a solution.

5. Try this one and check with your partner:
Determine whether each ordered pair is a solution of y = 4x – 1.
(10, 3)‏
y = 4x – 1
3 = 4(10) – 1 ?
Substitute 10 for x and 3 for y.
Simplify.
3 ≠ 39 
(10, 3) is not a solution.

6. Try this one by yourself:
Determine whether each ordered pair is a solution of y = 5x + 3.
(7, 38)‏
y = 5x + 3
38 = 5(7) + 3 ?
Substitute 7 for x and 38 for y.
38 = 38 ? 
(7, 38) is a solution.

7. Just in case we need another…
Determine whether each ordered pair is a solution of y = 5x + 3.
(9, 17)‏
y = 5x + 3
17 = 5(9) + 3 ?
Substitute 9 for x and 17 for y.
17 = 48 ? 
(9, 17) is not a solution.

8. Work out this example along with me:
Use the given values to make a table of solutions.
y = x + 3 for x = 1, 2, 3, 4 x
x + 3 y
(x, y)‏ 1 2 3 4
1 + 3 4
(1, 4)‏
2 + 3 5
(2, 5)‏
3 + 3 6
(3, 6)‏
4 + 3 7
(4, 7)‏

9. Work out this example with your partner:
Use the given values to make a table of solutions.
n = 6m – 5 for m = 1, 2, 3 m 1 2 3
6m – 5 n
(m, n)‏
6(1) – 5
(1, 1)‏ 1
6(2) – 5 7
(2, 7)‏
6(3) – 5 13
(3, 13)‏

10. Try doing this one by yourself:
Use the given values to make a table of solutions.
y = x + 6 for x = 1, 2, 3, 4 x
x + 6 y
(x, y)‏ 1 2 3 4
1 + 6 7
(1, 7)‏
2 + 6 8
(2, 8)‏
3 + 6 9
(3, 9)‏
4 + 6 10
(4, 10)‏

11. Do you have the learning targets mastered?

12. In the last box of your note page:
Determine whether each ordered pair is a solution of y = 4x – 7.
1. (2, 15) (4, 9)‏
3. Use the given values to make a table of solutions. y = 4x  6 for x = 2, 4, and 6 no
yes ‏
(6, 18)‏ 18
4(6) – 6 6
(4, 10)‏ 10
4(4) – 6 4
(2, 2)‏ 2
4(2) – 6
(x, y)‏ y
4x – 6 x
