Constant Proportionality on Tables, Equations, and Graphs

The graph shows the distance a plane travels. What does the point (2, 10) on the graph represent?

• The plane travels 2 miles in 10 minutes.

• The plane travels 10 miles in 1 minute.

• The plane travels 10 miles in 2 minutes.

• The plane does not travel at a constant rate.

The cost for 2 lbs of apples is $1.84. Reduce the ratio to determine the equation, where x is the lbs of apples and y is the cost.

• y = .92x

• x = .92y

• y = 2x

• y = 1.84x
