Understanding Linear Functions

What is the main objective of the lesson on linear functions?

• To explore polynomial functions

• To represent linear functions using tables and graphs

• To learn about quadratic functions

• To understand trigonometric functions

In the example of the Lockheed SR71 Blackbird, what does the variable 'x' represent?

• The fuel consumption

• The minutes traveled

• The distance traveled

• The speed of the aircraft

What is the function rule for the distance traveled by the Lockheed SR71 Blackbird?

• y = 36 and 610 + x

• y = 36 and 610 - x

• y = 36 and 610 * x

• y = 36 and 610 / x

In the farmers market example, what does the function y = 10 - 2x represent?

• The price per pound of apples and oranges

• The weight of apples and oranges

• The number of apples and oranges that can be purchased

• The cost of apples and oranges

How many pounds of oranges can Margerie purchase if she buys 2 pounds of apples?

• 2 pounds

• 4 pounds

• 6 pounds

• 10 pounds

What is the first step in graphing the function y = x - 5?

• Select any four values for the domain X

• Draw the graph

• Calculate the slope

• Find the y-intercept

For the function y = x - 5, what is the y-value when x = 0?

• 10

• 5

• 0

• -5

When graphing y = -2x, what is the y-value when x = -1?

• 4

• 2

• -2

• 0

What should you do if a value does not fit on the graph when plotting y = -2x?

• Change the scale of the graph

• Recalculate the value

• Ignore the value and move to the next one

• Use a different function

What is the importance of writing the equation on the graph?

• To make the graph look complete

• To identify the function being graphed

• To ensure accuracy in calculations

• To provide a reference for future graphs
