Learn how to graph a horizontal line by using a table

The video tutorial explains the concepts of slope and Y-intercept, focusing on zero slope. It demonstrates how to graph lines using a table of values, emphasizing horizontal and vertical lines. The tutorial concludes with a summary and invites questions.

What is the slope of the line represented by the equation Y = 0 * X - 2?

• 0

• 1

• Undefined

• -2

How can you graph a line using a table of values?

• By plotting random points

• By using only positive X values

• By selecting arbitrary X values and calculating corresponding Y values

• By using only negative Y values

What type of line is formed when Y equals a constant value?

• Curved line

• Horizontal line

• Diagonal line

• Vertical line

If X equals a constant value, what type of line is represented?

• Vertical line

• Diagonal line

• Horizontal line

• Curved line

What happens to the Y value when X changes in the equation Y = -2?

• Y changes with X

• Y becomes zero

• Y remains constant

• Y becomes undefined
