To solve this problem, we need to understand how to read a coordinate grid. The grid has an x-axis (the horizontal line at the bottom) and a y-axis (the vertical line on the left).
An ordered pair is written as
(x, y).
1.
First number (x): Start at 0 on the bottom axis and move right to find the column.
2.
Second number (y): Start at 0 on the side axis and move up to find the row.
The point where the column and row meet is the location of the item.
Part A: Write the ordered pair for each item.
1)
Pineapple:
* Look along the bottom axis: It lines up with
4.
* Look along the side axis: It lines up with
2.
* Ordered Pair:
(4, 2)
2)
Onion:
* Look along the bottom axis: It lines up with
8.
* Look along the side axis: It lines up with
1.
* Ordered Pair:
(8, 1)
3)
Apple (Red):
* Look along the bottom axis: It lines up with
4.
* Look along the side axis: It lines up with
9.
* Ordered Pair:
(4, 9)
4)
Eggplant:
* Look along the bottom axis: It lines up with
1.
* Look along the side axis: It lines up with
10.
* Ordered Pair:
(1, 10)
5)
Broccoli:
* Look along the bottom axis: It lines up with
9.
* Look along the side axis: It lines up with
5.
* Ordered Pair:
(9, 5)
Part B: Write the item located at each ordered pair.
6)
(2, 2):
* Go right to
2 on the bottom axis.
* Go up to
2 on the side axis.
* The item there is a
Tomato.
7)
(9, 7):
* Go right to
9 on the bottom axis.
* Go up to
7 on the side axis.
* The item there is a
Pear (yellow fruit).
8)
(2, 7):
* Go right to
2 on the bottom axis.
* Go up to
7 on the side axis.
* The item there is a
Watermelon.
9)
(3, 4):
* Go right to
3 on the bottom axis.
* Go up to
4 on the side axis.
* The item there is a
Beet (purple root vegetable).
10)
(7, 3):
* Go right to
7 on the bottom axis.
* Go up to
3 on the side axis.
* The item there is a
Potato (or red root vegetable).
Final Answer:
A)
1) (4, 2)
2) (8, 1)
3) (4, 9)
4) (1, 10)
5) (9, 5)
B)
6) Tomato
7) Pear
8) Watermelon
9) Beet
10) Potato
