You are walking directly away from your house. You are 5 miles away from your house when you start walking, so you can determine your distance from your house by adding 5 to the number of miles you have
walked. In the equation below, z represents the number of miles you have walked, and y represents your
distance from home in miles.
The relationship between these two variables can be expressed by the following equation:
y = x + 5
Identify the dependent and independent variables.
