how to graph vertical lines of a linear equation, x = -1

The video tutorial explains how to graph vertical and horizontal lines, focusing on equations that cannot be expressed in the slope-intercept form Y = MX + B. The instructor emphasizes using a table of values to graph such equations, specifically demonstrating with X = -1. The tutorial highlights that when X equals a constant, it forms a vertical line, and when Y equals a constant, it forms a horizontal line. The video aims to help students recognize patterns in graphing these lines.

What is a common reason students forget how to graph vertical and horizontal lines?

• They involve complex calculations.

• They are rarely used in real life.

• They require memorizing many formulas.

• They are not in the form Y = MX + B.

When graphing the equation X = -1, what remains constant?

• The intercept on the Y-axis

• The value of X

• The slope of the line

• The value of Y

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

• A curved line

• A vertical line

• A diagonal line

• A horizontal line

If Y equals a constant value, what type of line is produced?

• A zigzag line

• A diagonal line

• A horizontal line

• A vertical line

What is the result when an equation is in the form Y = a number?

• A curved line at the Y value

• A vertical line at the Y value

• A horizontal line at the Y value

• A diagonal line at the Y value
