• y = 2x+3

• y = 3x+3

• y = -2x+3

Find the function rule.

• y = -2x +10
• y = -2x -10
• y = 2x +10

Write the function rule for the following table.

•  5x
• 5x + 1
•  x + 5
•  x + 1

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Write the equation of the function shown in the table.

• y= 5x+5

• y=1/5x+5

• y=15x+5

• y=10x+5

Patrick earns $20 for every lawn that he mows. Write an equation used to find t, the total amount of money he earns from mowing n lawns.
