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.

What is the parent function of a linear graph?

• y = x

• y = x^2

• y = 1/x

• y = 2x + 3

When creating a table of values for y = x, what is the y-value when x is -2?

• 1

• 2

• 0

• -2

Which of the following x-values is NOT used in the table of values for y = x?

• 3

• -1

• 2

• 0

What is the first step in graphing the linear function y = x?

• Plot the origin (0,0)

• Plot the point (2,2)

• Draw the x-axis only

• Draw a parabola

How does the graph of the identity function y = x extend?

• It forms a closed loop

• It curves upwards

• It continues infinitely

• It stops at (2,2)
