Coordinate Plane Basics

Front

Define coordinate plane

Back

A coordinate plane is a two-dimensional surface formed by two number lines intersecting at a right angle. The horizontal number line is called the x-axis, and the vertical number line is called the y-axis.

Front

How many quadrants are in a coordinate plane

Back

There are four quadrants in a coordinate plane.

Front

What is the vertical axis called

Back

The vertical axis is called the y-axis.

Front

What is the horizontal axis called

Back

The horizontal axis is called the x-axis.

Front

How do you write an ordered pair

Back

An ordered pair is written in the form (x, y), where x is the value on the x-axis and y is the value on the y-axis.

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 purpose of the coordinate plane

Back

The coordinate plane is used to graphically represent algebraic equations and to locate points in a two-dimensional space.

Front

How do you plot a point on the coordinate plane

Back

To plot a point, locate the x-value on the x-axis and the y-value on the y-axis, then draw a point where these values intersect.

Front

What is the first quadrant in a coordinate plane

Back

The first quadrant is the section of the coordinate plane where both x and y values are positive.

Front

What is the second quadrant in a coordinate plane

Back

The second quadrant is the section of the coordinate plane where x values are negative and y values are positive.
