Equation: f(x) = 2x + 3

Which equation below will shift the graph of the equation above up 3 units?

• f(x) = 5x + 3

• f(x) = 5x - 3

• f(x) = 2x + 6

• f(x) = 2x - 6

The table shows x-values going in and y-values coming out. The function being used is

• f(x) = x + 4

• f(x) = x - 4

• f(x) = 2x - 2

• f(x) = 2x + 2

A student was asked to graph 2x - 2y = -4 by using slope and y-intercept. Her graph is shown. Which choice supports the graph that they have drawn?

How can you determine if data in a function table is linear?

• By checking if the x-values are in alphabetical order
• By counting the number of vowels in the x-values
• By calculating the average of the x-values
• By checking if the differences in the y-values are constant for each unit change in the x-values.
