Understanding Perpendicular Lines and Graphing

The video tutorial explains how to find an equation of a line that is perpendicular to x = -3 and passes through the point (5, 2). It begins by recognizing that x = -3 is a vertical line and demonstrates this by graphing it using a table of values. The tutorial shows how to plot points on the coordinate plane, specifically (-3, 0) and (-3, 2), to illustrate the vertical line. The conclusion reaffirms that x = -3 is indeed a vertical line.

What is the equation of a line that is perpendicular to x = -3?

• x = -3

• y = -3

• y = 5

• x = 5

Which of the following is true about the line x = -3?

• It is a vertical line.

• It is a diagonal line.

• It is a curved line.

• It is a horizontal line.

When graphing the line x = -3, what can the y-coordinate be?

• Only 0

• Only 2

• Any value

• Only negative values

What is the x-coordinate for all points on the line x = -3?

• Any value

• 0

• 3

• -3

After plotting the points, what do we confirm about the line x = -3?

• It is a horizontal line.

• It is a vertical line.

• It is a diagonal line.

• It is a circular line.
