Graphing Points Practice

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). It is used to graph points, lines, and curves.

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 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

How do you identify the quadrant of a point?

Back

To identify the quadrant of a point (x, y), check the signs of x and y: if both are positive, it's in Quadrant I; if x is negative and y is positive, it's in Quadrant II; if both are negative, it's in Quadrant III; if x is positive and y is negative, it's in Quadrant IV.

Front

What does the x-coordinate represent?

Back

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

Front

What does the y-coordinate represent?

Back

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

Front

How do you plot a point on a coordinate plane?

Back

To plot a point (x, y), start at the origin (0, 0), move x units along the x-axis, and then move y units up (if y is positive) or down (if y is negative).

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 ordered pair (0, 0).

Front

What is the significance of the first quadrant?

Back

In the first quadrant, both x and y coordinates are positive, which means all points in this quadrant represent positive values.

Front

What is the significance of the second quadrant?

Back

In the second quadrant, x coordinates are negative and y coordinates are positive, indicating points that are to the left of the y-axis and above the x-axis.
