Graphing on coordinate plane

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair of numbers (x, y).

Front

What does the ordered pair (x, y) represent?

Back

In the ordered pair (x, y), 'x' represents the horizontal position (left or right) and 'y' represents the vertical position (up or down) on the coordinate plane.

Front

How do you plot the point (4, -6) on a coordinate plane?

Back

To plot (4, -6), start at the origin (0, 0). Move 4 units to the right (positive x-direction) and then 6 units down (negative y-direction).

Front

What are the four quadrants of a coordinate plane?

Back

Quadrant I: (+, +), Quadrant II: (-, +), Quadrant III: (-, -), Quadrant IV: (+, -).

Front

Which quadrant contains the point (2, 5)?

Back

Quadrant I, because both x and y are positive.

Front

What direction do you move first when plotting the point (7, -7)?

Back

You move right (positive x-direction) first, then down (negative y-direction).

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate means the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate means the point is located below the origin on the y-axis.
