If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c ?
Accepted Solution
A:
To answer this question, we must find the slope of line b. We have then: b = (3 - (- 2)) / (2 - (- 3)) b = 5/5 b = 1 Since the lines b and c are parallel, it follows that their slopes are equal. Then mc = b = 1 Answer: The slope of line c is: mc = 1
