Writing the equation of a line perpendicular to another through a given point

What is the relationship between the slopes of parallel lines?

• They intersect at a right angle.

• One is positive, the other is negative.

• They are opposite reciprocals.

• They are equal.

How do you determine the slope of a line perpendicular to another with a slope of 2/3?

• 3/2

• -3/2

• -2/3

• 2/3

What is the advantage of using point-slope form?

• It does not require knowledge of the slope.

• It is easier to use when you have a point and a slope.

• It always results in a simpler equation.

• It is the only method for finding the equation of a line.

What is the result of applying the distributive property to 3/2 * (X - 6)?

• 3X - 6

• 3/2X + 9

• 3/2X - 9

• 3X + 6

Why is it important to verify that lines are perpendicular?

• To confirm they have the same y-intercept.

• To ensure they have opposite reciprocal slopes.

• To check if they are parallel.

• To determine if they are identical.
