Coordinate Graphing

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does the first number in an ordered pair represent?

Back

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

Front

What does the second number in an ordered pair represent?

Back

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

Front

What is the Y-axis?

Back

The Y-axis is the vertical axis on the coordinate plane, where the x-value is zero.

Front

What is the X-axis?

Back

The X-axis is the horizontal axis on the coordinate plane, where the y-value is zero.

Front

How do you locate a point on a coordinate plane?

Back

To locate a point, start at the origin (0,0), move along the x-axis to the x-value, and then move vertically to the y-value.

Front

What is the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the X-axis and Y-axis intersect.

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

What is the coordinate of point T if it is located 3 units left and 2 units down from the origin?

Back

The coordinate of point T is (-3, -2).

Front

If a point has coordinates (-4, 6), what is its location?

Back

The point is located 4 units left and 6 units up from the origin.
