Write the equation of a perpendicular line using point slope form

The video tutorial explains how to find the equation of a line that is perpendicular to a given line and passes through a specific point. It covers the properties of perpendicular lines, such as intersecting at a 90-degree angle and having opposite reciprocal slopes. The tutorial demonstrates using the point-slope form to derive the equation, applying the distributive property, and solving for the final equation.

What is a key characteristic of the slopes of perpendicular lines?

• They are both negative.

• They are equal.

• They are opposite reciprocals.

• They are both positive.

If a line has a slope of 4, what would be the slope of a line perpendicular to it?

• -1/4

• 1/4

• -4

• 4

Which form of the equation is used to find a line passing through a specific point?

• Point-slope form

• Slope-intercept form

• Quadratic form

• Standard form

What is the point-slope form of a line equation?

• Ax + By = C

• y = ax^2 + bx + c

• y - y1 = m(x - x1)

• y = mx + b

What is the final equation of the line that is perpendicular to y = 4x + 2/3 and passes through the point (8, 5)?

• y = 4x + 7

• y = -1/4x + 7

• y = -4x + 7

• y = 1/4x + 7
