indicate whether the lines are parallel, perpendicular, or neither justify your answer.


x-7y=10 and 2x+14y=21

Answer 1

The answer to your question is: neither parallel nor perpendicular.

Explanation:

Data

x - 7y = 10 ---(1) and 2x + 14y = 21 ---- (2)

First we need to clear y from two equations

7y = x -10 14y = -2x +21

y = x/7 - 10/7 y = -2/14 x + 21/14

y = -1/7 x + 3/2

slope = 1/7 slope = -1/7

They are neither parallel nor perpendicular, if they were parallel the slopes will be the same, if they were perpendicular they would have inverse values.
