The table represents a proportional relationship with the number of nails in boxes. What are the unknown values representing the unit rate?a =
b =
Based on the data, which table shows a constant of proportionality of 2 for the ratio of granola to raisins?
The graph represents the price of tomatoes at one store. What is the unit rate?$ per pound
Jeremy looked at this table of prices and said the cost for renting a bike is $7.00 per hour. What mistake may Jeremy have made? Explain.
Jeremy mistook the $7.00 cost for 2 hours as the cost for 1 hour. The unit rate is found by dividing cost by hours: $7.00 ÷ 2 = $3.50 per hour. The other pairs in the table also give $3.50 per hour.
Explain how you can find the constant of proportionality from a graph representing a proportional relationship when it shows a point with an x-value of 1 and if it doesn’t show an x-value of 1.
When the x-value is 1 , the y-value is the constant of proportionality. If there isn’t an x-value of 1, choose another point and divide the y-value by the x-value to find the constant of proportionality.
