Say for example you paid $2 or a 1 km ride.into function notation "cost is a function of distance" or cost(distance). now translating this to a mathematical equation. we know that cost is directly proportional to the distance traveled. this describes linear relationship.y=mx + b is the standard equation of a line. where m is the slope (or rate).y = ($2/1km)x + b
