Lesson 8.2 - Coordinate Graphs

Front

What is a coordinate graph?

Back

A coordinate graph is a two-dimensional space where points are defined by pairs of numbers (x, y) that represent their position on the horizontal (x-axis) and vertical (y-axis) lines.

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position of a point on a coordinate graph.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position of a point on a coordinate graph.

Front

How do you correctly write an ordered pair?

Back

An ordered pair is written as (x, y), where x is the x-coordinate and y is the y-coordinate.

Front

What is the origin in a coordinate graph?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

What is the distance from the origin to the point (3, 4)?

Back

The distance is 5 units, calculated using the Pythagorean theorem: √(3² + 4²) = √(9 + 16) = √25 = 5.

Front

Which quadrant is the point (2, 3) located in?

Back

The point (2, 3) is located in Quadrant I, where both x and y coordinates are positive.

Front

What is the ordered pair for the point located 4 units right and 2 units up from the origin?

Back

The ordered pair is (4, 2).

Front

If a point has an x-coordinate of 0, where is it located?

Back

If a point has an x-coordinate of 0, it is located on the y-axis.

Front

If a point has a y-coordinate of 0, where is it located?

Back

If a point has a y-coordinate of 0, it is located on the x-axis.
