solver:
Finding the slope
Slope of the line through the points (9, 2) and (3, -8)
Answer: Slope is
Now find the slope through (–3, 5) and (5, –1)
Solved by

solver:
Finding the slope
Slope of the line through the points (-3, 5) and (5, -1)
Answer: Slope is
Since the slopes are not equal and are not negative reciprocals of one another, they are neither parallel nor perpendicular.
