Coordinate Pairs

Front

What is a coordinate pair?

Back

A coordinate pair is a set of two numbers that define a point on a coordinate plane, written in the form (x,y).

Front

What does the first number in a coordinate pair represent?

Back

The first number in a coordinate pair represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

Front

What does the second number in a coordinate pair represent?

Back

The second number in a coordinate pair represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you identify the x-axis on a coordinate plane?

Back

The x-axis is the horizontal line on the coordinate plane where the y-coordinate is 0.

Front

How do you identify the y-axis on a coordinate plane?

Back

The y-axis is the vertical line on the coordinate plane where the x-coordinate is 0.

Front

What is the coordinate of a point located 3 units to the right and 2 units up from the origin?

Back

The coordinate of that point is (3,2).

Front

If a point has coordinates (4,0), where is it located?

Back

The point (4,0) is located on the x-axis, 4 units to the right of the origin.

Front

If a point has coordinates (0,-5), where is it located?

Back

The point (0,-5) is located on the y-axis, 5 units down from the origin.

Front

What is the distance between the points (2,3) and (2,-1)?

Back

The distance is 4 units, as they are vertically aligned on the same x-coordinate.
