For example, students can use a ruler marked in both centimeters and inches to identify the constant factor (the number of centimeters in a given length is about 2.5 times the number of inches in a given length) and describe the relationship between the number of centimeters (y) and the number of inches (x) in a given measurement: y = 2.5x. Clarifying Activity Students use the scale of a map to represent the relationship between the distance on the map and the actual distance between two points.
