Exploring Linear Transformations

The video tutorial focuses on graphing parent functions, specifically y = x, and explores how changes in the slope and y-intercept affect the graph. It explains the concept of parent functions, how to graph them, and how to shift the graph vertically by altering the y-intercept. Additionally, it covers how changing the slope can make the graph steeper or flatter, introducing terms like vertical stretch and compression.

What is the parent function of a linear equation?

• y = 2x + 1

• y = x

• y = 3x - 2

• y = -x + 4
