Patterns, Equations and Graphs

Nancy can type 50 words per minute. Look at the table below to write an equation that matches the data.

• m=50 + w

• w= 50m

• w= 50 + m

• m= 50 - w

Is the pattern in the graph additive or multiplicative? Explain.

• Additive; the y-values start at 0 and they increase by multiples of 4

• Multiplicative; the y-values start at 0 and they increase by multiples of 4

• Additive; the y-values do not start at 0 and they increase by multiples of 4

• Multiplicative; the y-values do not start at 0 and they increase by multiples of 4

Kelly sold T-shirts to earn extra money. The graph shows the number of T-shirts she sold and the amount of money she earned.

Which statement about the pattern shown in the graph is true?

• The graph represents an additive pattern because it shows x = y + 3.

• The graph represents an additive pattern because it shows y = x + 3.

• The graph represents a multiplicative pattern because it shows y = 3x.

• The graph represents a multiplicative pattern because it shows x = 3y.

• F

• G

• H

• J

The ordered pairs shown on the coordinate plane below consist of the corresponding terms from two numerical patterns. Which two rules would generate these patterns?

• For x use the rule “Add 2” and the starting number 1. For y use the rule “Add 3” and the starting number 1.

• For x use the rule “Add 3” and the starting number 1. For y use the rule “Add 2” and the starting number 1.

• For x use the rule “Add 2” and the starting number 0. For y use the rule “Add 3” and the starting number 0.

• For x use the rule “Add 3” and the starting number 0. For y use the rule “Add 2” and the starting number 0.
