Pattern Table and Equation

What is the equation of the graph?

• y = 3x - 4

• y = 3x + 2

• y = 2x + 3

• y = -2x - 4

What is the growth / rate of change of the table?

• m = 3

• m = 9

• m = 21

• m = 1

What is the value at figure zero?

• b = 0

• b = 9

• b = 6

• b = 21

What is the equation?

• f(x) = 2x + 0

• f(x) = 2x + 2

• f(x) = 1x + 2

• f(x) = 2x + 1

Jay’s teacher gave him an input number and a rule for a numerical pattern. Jay wrote an output number using the rule as shown in the table. Which statement about the pattern in Jay’s table is true?

• The pattern is additive because the input plus 246 equals the output.

• The pattern is multiplicative because the input times 3 equals the output.

• The pattern is additive because the input plus 75 equals the output.

• The pattern is multiplicative because the input times 2 equals the output.

Lyle learned that a hummingbird can beat its wings up to 70 times per second. He made the table shown to determine the number of times a hummingbird would beat its wings over several seconds.

Which statement about the numerical pattern in the table is true?

• The table shows an additive pattern because the number of beats is 69 more than the number of seconds.

• The table shows an additive pattern because the number of beats is 70 more than the number of seconds.

• The table shows a multiplicative pattern because the number of beats is 69 times the number of seconds.

• The table shows a multiplicative pattern because the number of beats is 70 times the number of seconds.

Shae is 6 years older than her sister Ashanti. The relationship between Shae’s age and Ashanti’s age can be represented by the equation y = x + 6.

Which table could represent this relationship?

• 
• 
• 
• 

Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 0

Which of the equations can be used to describe the pattern in the table?

• 5x = y

• x + y = 5

• x - y = 5

• x ÷ y = 5
