Concept 1: How to determine if two lines are parallel?
If two lines have the same slope, then they are parallel.
Are these two lines parallel?
Concept 2: Writing Equations of Parallel Lines
What is the equation of the line parallel to y = -3x - 5 that passes through (-1, 8)?
Concept 3: How to determine if two lines are perpendicular?
If two lines are perpendicular, the product of their slopes is -1. This means they are "opposite reciprocals."
Are these two lines perpendicular?
Concept 2: Writing Equations of Perpendicular Lines
What is the equation of the line parallel to y = 1/5x + 2 that passes through (15, -4)?
