If a person swims at a constant speed of 1 meter per second, than the linear function will be used to model the distance travelled by the swimmer.
The parent function is "the principal's of ice"
A linear function is a function that forms a straight line on a graph. It is generally a polynomial function whose degree is at most 1 or 0. Although linear functions are also represented in terms of calculus and linear algebra.
Here Y-axis represents Distance and X-axis represents Time.
Also speed is the rate of change of distance with respect to time i.e. distance is changing linearly with time
Mathematically it is
.
Change in Distance = Change in time and hence speed is constant.
