In this lesson, we will learn how to use the concept of slopes to determine whether two lines are parallel or perpendicular and use these geometric relationships to solve problems.
Students will be able to
Q1:
Two lines are perpendicular. What will the product of their slopes be?
Q2:
If the line passing through points 𝐴(−13,8) and 𝐵(20,𝑦) is parallel to the line passing through points 𝐶(−2,0) and 𝐷(7,𝑦), what is the value of 𝑦?
Q3:
Two lines 𝐴 and 𝐵 have slopes of 75 and −57 respectively. Are the two lines perpendicular?
