A man went running. He ran a total of 31 km at a constant speed of 9 km per hour. Shows the graph below.
The Graph above is increasing gradually because as the time passes the distance is getting larger.
Dependent Independent and Constant
The constant in the graph is 9 km per hour. The dependent variable is the distance and the independent variable is the time.
Independent Variable - A variable that does not depend on another
Dependent Variable - A variable that changes because it depends on another
Constant - A number that stays the same or is constant
