Coordinate Planes

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 locate points using ordered pairs.

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to locate points on a coordinate plane, written in the form (x, y), where x is the x-coordinate and y is the y-coordinate.

Front

What is the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair, representing the horizontal position on the coordinate plane.

Front

What is the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair, representing the vertical position on the coordinate plane.

Front

How do you identify the y-coordinate in the ordered pair (4, 9)?

Back

The y-coordinate is 9, which is the second number in the ordered pair.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How do you write an ordered pair?

Back

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

Front

What is the purpose of a coordinate plane?

Back

The purpose of a coordinate plane is to provide a visual representation of mathematical relationships and to locate points using ordered pairs.

Front

What is the first step in plotting a point on a coordinate plane?

Back

The first step is to locate the x-coordinate on the x-axis.
