Answer:
Second answer, 3y-5x=20
Explanation:
Perpendicular lines have slopes that are opposite recipricols. in other words, when you multiply the slopes of the two lines, they must equal -1. To find the slope then, you need to do:
-1/(-3/5)
An easier way to do it is to flip the negative/positive sign ( - <=> +) and flip the numerator and denominator.
In this equation, it looks like this:
flip -3/5, which equals -5/3.
divide by -1, which gives us a final answer of 5/3.
We need a line with a slope of 5/3.
I think that you know how to find slope, but if you don't, feel free to comment to ask for details.
