Question

The drill team is buying new uniforms. The table shows y, the total cost in dollars, and x, the number of uniforms purchased.

The data is : 1 to 60, 3 to 180, 5 to 300, and 9 to 540.

a. Use the data table ^ to draw a graph. Is the relationship between x and y linear? explain.

b. Use your graph to predict the cost of purchasing 12 uniforms

Answer 1

A: Yes, the relationship is linear.

Explanation:

1=60, so we can assume that 3=180 because 60x3=180. we can use this strategy for the rest of the data and confirm that the line has a consistent slope of 60/1.
