How do you graph y equals 100 over x on a graph in algebra?

Answer 1

If you know what a graph of 1/x looks like, you have a good start. Just make your y units a 100 times bigger (write 100 where you'd normally write 1 and so on) and you've got a graph of y=100/x.

If you don't know what 1/x looks like, I would suggest looking it up. It's good to know for future reference.

If you are really stuck, it will almost always work out to just plot a few points and connect them with a line. Just recognize that for 100/x there is a discontinuity at 0 (since you can't divide by 0) and that there are no points in the second and fourth quadrants. At zero, the graph flies off to infinity on

the positive side and off to negative infinity on the negative side. There should not be any

lines drawn across the y axis.
