Question

xy=15

Answer 1

x could be 1 and y could be 15
x could be 3 and y could be 5
y could be 1 and x could be 15
y could be 3 and x could be 5

are you sure this is all of the problem?

Answer 2

it says graph each invers variation.

Answer 3

well if you divide both sides by x you would have \[y=\frac{ 15 }{ x }\]

Answer 4

so thats the answer for the graph. all you have to do is dived both sides by x

Answer 5

well the graph looks like this

Answer 6

If you have to graph it by hand do this
x y
-5 -3
5 3
1 15
-1 -15



etc. I am plugging in an x into the equation to find the y value. When you have the two values you can plot them on a graph and then connect them with a line.
