16-1 Practice

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 write an ordered pair?

Back

An ordered pair is written as (X,Y), where X is the horizontal coordinate and Y is the vertical coordinate.

Front

Which ordered pair represents the point where X is 2 and Y is 8?

Back

(2,8)

Front

What does the point (0,9) represent on a graph?

Back

The point (0,9) is located on the y-axis.

Front

What is the significance of the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line on a graph where the value of Y is 0.

Front

What is the significance of the y-axis in a coordinate plane?

Back

The y-axis is the vertical line on a graph where the value of X is 0.

Front

What does it mean if a graph shows a multiplicative pattern?

Back

A multiplicative pattern means that one variable is a constant multiple of another, often represented as y = kx, where k is a constant.

Front

What does it mean if a graph shows an additive pattern?

Back

An additive pattern means that a constant is added to one variable to get the other, often represented as y = x + b, where b is a constant.

Front

If Kelly sold T-shirts and the graph shows y = 3x, what does this indicate?

Back

This indicates that for every T-shirt sold (x), Kelly earned 3 times that amount in money (y).

Front

How can you identify the location of a point on a graph?

Back

You can identify the location of a point by its ordered pair (X,Y), where X indicates the horizontal position and Y indicates the vertical position.
