Q:

Need help on this question please indicate whether the lines are parallel, perpendicular, or neither justify your answer.x-7y=10 and 2x+14y=21

Accepted Solution

A:
Answer:The answer to your question is: neither parallel nor perpendicular.Step-by-step 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 +21y = x/7 - 10/7                                             y = -2/14 x + 21/14                                                                  y = -1/7 x + 3/2slope = 1/7                                               slope = -1/7They are neither parallel nor perpendicular, if they were parallel the slopes will be the same, if they were perpendicular they would have inverse values.
