Objective:
To find the slope of a line and to determine whether two lines are parallel, perpendicular, or neither.
A line l has equation x + 2y = 5. What is the slope of a line (a)
parallel to l? (b) perpendicular to l?
The equations of three lines are given. Which lines are parallel and
which are perpendicular?
a. y = ¾ x – 7b. 4x + 3y = 10 c. 3x – 4y = 11
Find the value of k if the line joining (2, k) and (4, 5) and the line y = 3x + 1 are (a) parallel,
(b) perpendicular.
