What is the parent function of a linear graph

The video tutorial explains the basics of graphing linear equations, focusing on the parent function y = x, known as the identity function. It demonstrates how to create a table of values to find coordinate points and plot them on a graph. The tutorial guides viewers through the process of graphing a linear function by plotting points and drawing a straight line, emphasizing the concept of the parent function without transformations.

Describe the process of graphing the points for the linear function.
