Question

prepare for representing proportional relationships

1. think about what you know about graphing. fill in each box. use words, numbers and pictures. show as many ideas as you can

word	in my own words	example
y - coordinate
ordered pair
origin

1. fadi says that the ordered pair for the point shown is (7, 5). explain why fadi is incorrect

Explanation:

• x - coordinate: Horizontal position on graph. Example: In (3, 4), 3 is x - coordinate.
• y - coordinate: Vertical position on graph. Example: In (3, 4), 4 is y - coordinate.
• Ordered pair: Pair of numbers (x, y) for a point. Example: (2, 3).
• Origin: Point (0, 0) where axes meet.

Fadi is wrong as order matters in ordered pair.

Answer:

• x - coordinate: Horizontal position, e.g., in (3, 4), 3 is x - coordinate.
• y - coordinate: Vertical position, e.g., in (3, 4), 4 is y - coordinate.
• Ordered pair: A pair (x, y) for a point, e.g., (2, 3).
• Origin: The point (0, 0). Fadi is incorrect because order in ordered pair matters.
