Comparing Linear Functions and Their Properties

Mr. West presents a Khan Academy tutorial on comparing linear functions, requested by Muhammad Yahshua Khan. The video covers understanding and calculating slope and y-intercept, analyzing graphs, and comparing function increases. It concludes with an invitation for viewers to request more videos.

What is the main topic of the tutorial?

• Understanding calculus

• Comparing linear functions

• Solving quadratic equations

• Learning about geometry

How are linear functions represented in the tutorial?

• With 3D models

• Using tables and graphs

• Only with equations

• Through animations

What is the slope of a function?

• The area under the curve

• The rise over run

• The y-intercept

• The x-intercept

What is the general form of a linear equation?

• y = mx + b

• y = ax^2 + bx + c

• y = a/x

• y = x^2 + y^2

How is the slope calculated from a table?

• By adding all x-values

• By finding the difference in y-values divided by the difference in x-values

• By multiplying y-values

• By subtracting x-values from y-values

Which function increases faster?

• The one with the larger y-intercept

• The one with the larger slope

• The one with the smaller slope

• The one with the smaller y-intercept

What determines a greater y-intercept?

• The y-value where x is zero

• The slope of the line

• The length of the line

• The x-value at the intercept
