Functions and Linear Relationships

Where is the x-axis on a graph?

• The horizontal line on a coordinate plane.

• The vertical line on a coordinate plane.

• A set of numbers written in the form (x,y)

• A graph

Where is the y-axis on a graph?

• The horizontal axis on the coordinate plane

• The vertical axis on the coordinate plane

• The point where the horizontal and vertical lines cross

• A set of numbers written (x,y)

How is an ordered pair written?

• (x,x)

• (y,x)

• (x,y)

• (y,y)

What does an ordered pair represent?

• The slope

• The coordinates of a point

• The middle part of a graph

• A y-value

What is a relation?

• A set of ordered pairs

• A function

• A ratio

• The x-value in a function

Domain is...

• The set of y-values in a relation

• The set of x-values in a relation

• A vertical line

• A horizontal line

Range is...

• The set of y-values in a relation

• The set of x-values in a relation

• A ratio

• An ordered pair

Domain and Range are always written in this order.

• Greatest to least

• Least to greatest

• Only negative numbers

• Only positive numbers

What does the vertical line test tell us?

• The secrets of world peace

• If a graph is a function or not

• If a graph is a relation

• If the graph can have another line added to it

How is the slope of a line written?

• As an equation

• rise / run

• run / rise

• Run before you jump
