Write a function rule for the statement: The output is thirteen more than four times the input.

Find the function rule.

• y = 2x

• y = 2x+3

• y = 3x+3

• y = -2x+3

Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 5

Which equation best represents the relationship between x and y in the table shown?

• y= 5x+5

• y=1/5x+5

• y=15x+5

• y=10x+5

Find the function rule.

• y = -2x +10

• y = -2x -10

• y = 2x +10

• y = 2x-10

Which equation matches the table?

• y = x 

• y = 5x

• y = x - 4

• y = x + 4
