Comparing Slopes of Linear Functions

The video tutorial explains how to compare the slopes of two linear functions presented in different forms: an equation and a verbal description. It details how to identify the slope and constant in a linear equation and how to interpret a verbal description to determine the slope. The tutorial concludes by comparing the slopes to find the greater one.

What are we comparing in this problem?

• The slopes of two linear functions

• The y-intercepts of two functions

• The constants of two equations

• The variables of two functions

In a linear equation, what is the term called that does not change?

• Variable

• Slope

• Coefficient

• Constant

What is the slope of the given linear equation?

• Positive 5

• Zero

• Positive 3

• Negative 5

In the verbal description, what is the y-intercept?

• 2

• 3

• 12

• 5

How much does the function increase vertically in the verbal description?

• Four units

• Three units

• One unit

• Two units

What is the slope derived from the verbal description?

• Positive 3

• Positive 2

• Positive 1

• Positive 4

Which slope is greater, the one from the equation or the verbal description?

• The slope from the equation

• Cannot be determined

• The slope from the verbal description

• Both are equal

What is the value of the greater slope?

• 12

• 5

• 3

• 2

What is the key concept used to compare the slopes?
