Calculating Y Values from X

The video tutorial demonstrates how to create a table of values for the equation 4Y = 5x + 20. The instructor selects a range of X values (-2, -1, 0, 1, 2) and calculates the corresponding Y values by substituting each X value into the equation. The results are simplified and recorded in a table, providing a set of coordinate points that represent the equation graphically.

What is the purpose of creating a table of values for the equation 4Y = 5x + 20?

• To find the roots of the equation
