Linear Relations

A linear relation:

• is a straight line

• is a relationship between two variables

• can be described using slope and y-intercept

• all of the above

• none of the above

The rate of change of a linear relation is:

• the slope

• the y-intercept

• the equation of a line

• none of the above

• all of the above

The two key characteristics of a linear relation are:

• slope and initial value

• slope and y-intercept

• rate of change and initial value

• rate of change and y-intercept

• all of the above

This linear relation has

• a y-intercept of +2

• a positive slope

• a negative slope

• no y-intercept

This linear relation has

• a y-intercept of +2

• no slope

• a negative slope

• no y-intercept

This linear relation has

• a y-intercept of +2

• no slope

• a negative slope

• no y-intercept

The "Positive Slope" property states that:

• the line goes down

• two lines have the same slope

• the line goes up

• the line is steeper

The "Negative Slope" property states that:

• the line goes down

• two lines have the same slope

• the line goes up

• the line is steeper

The "Parallel Lines" property states that:

• the line goes down

• two lines have the same slope

• the line goes up

• the line is steeper

The "Higher Slopes" property states that:

• the line goes down

• two lines have the same slope

• the line goes up

• the line is steeper
