1. Each centimeter on a map represents 6 kilometers of real-world distance. What is the equation of the line that represents this relationship, where x represents the map distance in centimeters and y represents the real-world distance in kilometers?

• y = 6x

• y = x + 6

• y = x/6

• y = 6 + x

Does the graph shown represent a function? Explain.

• The graph represents a function because there is exactly one y-value for each x-value.

• The graph does not represent a function because there is exactly one y-value for each x-value.

• The graph represents a function because some x-values have more than one corresponding y-value.

• The graph does not represent a function because some x-values have more than one corresponding y-value.
