The pH scale is a measure of how acidic a solution is.
<h3>What is a pH scale?</h3>
The unit of measurement to determine how acidic or basic a solution is, is done via a pH scale, which ranged from 0 to 14, on which 0 to 6.9 means that the solution is acidic, and 7 is neutral.
Hence, the pH scale helps to determine the acidic amount of the solution.

Answer:
Inconsistent parallel lines is easiest pick k so the slopes (k) is the same as the first line.
It would be helpful to rewrite y-5x=-1 in y=mx+b where m is slope and b is y-intercept
y=5x-1 and y=kx+3 choose k=5 and you will get parallel lines and since the y intercepts are different they will be different parallel lines and inconsistent.
Now consistent intersecting lines are easy now you know the parallel solution is inconsistent so you can choose k to be what ever you want as long as it isn't 5, to make perpendicular just use -1/5.
