Tables Equations Graphs

The graph shows the distance a plane travels. Use one of the points on the graph to reduce to the unit rate.

• 5 miles per minute

• 5 minutes per mile

• 10 minutes per mile

• 10 miles per minute

Use the graph to determine an equation to represent the relationship. Use t for minutes (time), and m for miles.

• 5t = m

• 5m = t

Use the table to solve for the constant of proportionality.

• 3

• 6

• 2

Look at the graph, which ordered pair represents the unit rate?

• (0, 0)

• (1, 0.75)

• (4, 3)

• (8, 6)

Use a point on the graph to reduce to the unit rate.

• $7.50 per pound of chicken salad

• $1 per pound of chicken salad

• 7.5 pounds of chicken salad per dollar

• $15 for 2 pounds of chicken salad

Which equation would be use to create the graph above?

• y = 50x

• y = 2x

• y = 0.02x

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

What are the independent quantities in the table?

• {5,6,7,8,9}

• {0,1,2,3,4}

• x

• y

What rule would explain this input output table?

• The output is 3 times as much as the input.

• The input is 3 times as much as the output.

• The output is 8 times as much as the input.

• The input is 8 times as much as the output.

What is the algebraic equation for this table?

• y = 480x

• x = y/480

• x + 480 = y

• 480 - x = y
