Question

Line d passes through points (3, 4) and (8, 10). Line e is perpendicular to d. What is the slope of line e?

Answer 1

The slope of line e is -5/6

Explanation:

The slope of line d that passes through (3,4) and (8,10) is 6/5. To find the slope of a perpendicular line you simply change the sign and flip the numerator and denominator.
