Proportional Relationships Warm-Up

This graph is NOT proportional because . . .

• It has the same CoP

• It is not a continuous straight line

• It does not start at the origin (0,0)

Does the table represent a proportional relationship?

• Yes.
• No.

The constant of proportionality can be found by finding the __________  _____________.

• unit rate
• ratio rate
• proportion answer
• rational number

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
