Graph each ordered pair on a coordinate grid.
1. (–3, 3)
SOLUTION: To graph (–3, 3), start at the origin. Move 3 units to
the left and then up 3 units.
4. (–5, 5)
SOLUTION: To graph (–5, 5), start at the origin. Move 5 units to
the left and then up 5 units.
5. (0, 6)
2. (–2, 1)
SOLUTION: To graph (–2, 1), start at the origin. Move 2 units to
the left and then up 1 unit.
SOLUTION: To graph (0, 6), start at the origin. Move up 6 units.
6. (2, –1)
3. (3, 0)
SOLUTION: To graph (3, 0), start at the origin. Move 3 units to
the right.
SOLUTION: To graph (2, –1), start at the origin. Move 2 units to
the right and then down 1 unit.

Write the ordered pair for each point.
14. 8 – y = x
SOLUTION: 7. A
15. 5x – 2y = 12
SOLUTION: SOLUTION: To get to point A, move 3 units to the right and then
down 1 unit. So, the ordered pair is (3, –1).
8. B
SOLUTION: To get to point B, move 3 units to the left and then up
1 unit. So, the ordered pair is (–3, 1).
16. 3x + 4y = 10
SOLUTION: 9. C
SOLUTION: To get to point C, move 3 units to the right and then
up 2 units. So, the ordered pair is (3, 2).
10. D
SOLUTION: To get to point D, move 1 unit to the left and then
down 4 units. So, the ordered pair is (–1, –4).
17. SOLUTION: 11. F
SOLUTION: To get to point F, move 5 units to the right. So, the
ordered pair is (5, 0).
12. G
SOLUTION: To get to point G, move 1 unit to the left and then up
2 units. So, the ordered pair is (–1, 2).
18. SOLUTION: Solve each equation for y.
13. 3x + y = 1
SOLUTION: Evaluate
14. 8 – y = x

Evaluate
for each set of values.
19. a = 7, b = 6, c = 9, d = 5
SOLUTION: 20. a = –3, b = 0, c = 3, d = –1
SOLUTION: 21. a = –5, b = –5, c = 5, d = 8
SOLUTION: 22. a = –6, b = 3, c = 8, d = 2
SOLUTION: 23. MOVIES A movie made $297.2 million in 22 weeks.
How much did the movie make on average each
week?
SOLUTION: To find the average amount the movie made each
week, divide $297.2 million by 22 weeks.
297.2 ÷ 22 ≈ 13.5
So, the movie made about $13.5 million on average
each week.
