Word Problems
15 teachers get 6 markers each. How many markers is that?
90
What do parentheses tell you to do?
Solve inside them first.
What is the point where the x-axis and y-axis intersect called?
The origin (0,0)
Rule: y = x + 5. What is y when x = 3?
8
Graph (2,4). Which direction do you move first?
Move 2 units right first.
Write an equation: 120 markers were handed out. 15 teachers got 6 each and the art teacher got 9. The rest go to m.
120 = (15×6) + 9 + m
Simplify: (6 + 4) × 3
30
In the ordered pair (4,7), which number tells how far to move parallel to the x-axis?
4 (the x-coordinate)
Rule: y = 4x. What is y when x = 6?
24
Which ordered pair matches: move 5 right and 1 up?
(5,1)
Solve: 120 = (15×6) + 9 + m
m = 21
Simplify: [(8 + 2) × 5] ÷ 10
5
In the ordered pair (3,5), describe exactly how to graph the point.
Start at the origin, move 3 units right, then 5 units up.
Table shows:
1 → 7
2 → 8
3 → 9
Is this additive or multiplicative?
Additive (+6 from x)
The school is located at (6,2). Describe how to get there from (0,0).
Move 6 units right, then 2 units up.
A theater sells 300 tickets in 12 hours. How many in 30 hours?
750
Simplify: (24 ÷ 6) + (3 × 4)
4 + 12 = 16
Explain why the coordinate plane is made of perpendicular number lines.
The x-axis and y-axis intersect at right angles (the Origin), forming four quadrants.
Table shows:
1 → 5
2 → 10
3 → 15
Is this additive or multiplicative? Explain.
Multiplicative (×5)
A table shows:
x → 1, 2, 3
y → 4, 8, 12
Graph the points. What pattern do you notice?
Multiplicative pattern (×4).
Phil earns $24 + $18. Sarah earns triple that and spends $7.75. How much does she have left?
$118.25
[(4.75 + 1.25) × 8] ÷ 16
3
A point is 8 units right and 6 units up from the origin. What is the ordered pair, and why?
(8,6) first number is horizontal movement on the x-axis, second is vertical movement on the y-axis.
Create a rule for this pattern and identify if it is additive or multiplicative:
x: 0, 1, 2, 3
y: 4, 7, 10, 13
y = x + 4 (additive +3 pattern)
A real-world problem gives this rule: y = 3x. Graph the points when x = 2, 4, 6. What do you notice about the graph?
(2,6), (4,12), (6,18) — straight line pattern through origin.
