Find the line perpendicular to a line through a given point

The video tutorial covers the basics of parallel and perpendicular lines, focusing on writing equations in the form Y=MX+B. It explains how to find a perpendicular line through a given point by using opposite reciprocal slopes and calculating the Y-intercept. The tutorial concludes with deriving the final equation and emphasizing the importance of understanding opposite reciprocal slopes for perpendicular lines.

What is the standard form of a linear equation discussed in the video?

• Y = BX + A

• Y = CX + D

• Y = MX + B

• Y = AX + C

What is the relationship between the slopes of perpendicular lines?

• They are both positive

• They are opposite reciprocals

• They are equal

• They are both negative

If a line has a slope of 1/4, what is the slope of a line perpendicular to it?

• -1/4

• -4

• 1/4

• 4

What is the first step in finding the Y-intercept of a perpendicular line?

• Assume it is the same as the original line

• Use the slope-intercept form

• Plug in the given point into the equation

• Calculate the reciprocal of the slope

Why is the Y-intercept of a perpendicular line not necessarily the same as the original line?

• Because the perpendicular line passes through a different point

• Because the lines intersect at the origin

• Because the lines are parallel

• Because the slopes are different

What is the final equation of the perpendicular line discussed in the video?

• Y = X - 1

• Y = -X - 1

• Y = -X + 2

• Y = X + 2

What is the key concept to remember about perpendicular lines?

• They have the same slope

• They have opposite reciprocal slopes

• They never intersect

• They have the same Y-intercept
