Linear Equations and Tables

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 graph proportional or non proportional?

• proportional

• non proportional

• both

• neither

What is the equation of the line?

• y = 20x

• y = x + 20

• y = 2x

• y = x + 2

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

• c = 2.75b + 4

• c = 2.75b

• c =  4b- 2.75

• c = 2.75b - 4

You earn $18 for every hour you work. Which equation represents this function?

• y=(18/2)x + 0

• y = 18x

• y = 2x + 18

• y = 18x + 2

You are visiting Houston, Texas and a taxi cab company charges a flat rate of $4.00 for using the cab and $0.95 per mile.  Write an equation to determine the cost when x miles is driven.

• y = .75x

• y = .95x

• y = .95x + 4

• y=4.95x

The number of trees and the number of apples are given in the table above.  Determine which statement below is correct.

• The table is not proportional because the unit rate is not constant.

• The table is proportional and the unit rate is 1/13

• The table is proportional and the unit rate is 13.

• The table is not proportional because it doesn't pass through the origin.
