Algebra 2 Regular Quiz 2 Fall 2024

The graphs of linear equations are lines. There are four basic ways that lines travel. Put each answer option into the category where it belongs.

Groups:

(a) positive-sloped line

,

(b) negative-sloped line

,

(c) zero-sloped line

,

(d) no-sloped (undefined) line

• down, left

• down,right

• 
• vertical line

• has NO horizontal change

• 
• up,right

• horizontal line

• 
• 
• up,left

• has NO vertical change

Categorize each concept into either DOMAIN or RANGE.

Groups:

(a) DOMAIN

,

(b) RANGE

• y

• input

• output

• dependent variable

• Set of 2nd members of a relation.

• Set of 1st members of a relation.

• let to right on a graph

• A relation where each member of the range is paired with exactly two members of the domain.

• A relation where each member of the range is paired with exactly one member of the domain.

• A relation where each member of the domain is paired with exactly one member of the range.

• A set of ordered pairs.

• integers
• real number
