Question 52788: I have two questions. One is What is the slope of all horizontal lines? the other is What is the slope of all lines perpendicular to y= -5/2x? I'm trying to help my daughter with this and I can't make heads or tails out of the Algebra book. Thanks! Answer by antsinmypants(6) (Show Source):
You can put this solution on YOUR website! Hi there,
If you have a horizontal line, then that means that your slope is 0. This is because your x coordinates are all the same number.
To find the slope of all lines perpendicular to y=-5/2x, you need to find the negative reciprocal of the slope of y=-5/2x. In your case its done this way:
Using the forumla y=mx+b, m is the slope. so the slope given to you is -5/2 so the negative reciprocal, which is like an inverse of that. That would be 2/5.
so your answer to your second question is 2/5
:D There you go!
