Answer:
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! 1. Missing numbers
2. ...by definition? I assume you know what reciprocals are.
3. Find the slope of the line passing through (14,5) and (19,5). The slope of a perpendicular line is the negative reciprocal of the slope you just computed. Use the point-slope form to determine the equation.
4. Almost always. The only exception is if one line is vertical and the other is horizontal, in which the product of their slopes is undefined.
