Question 482826
The variables x and y vary inversely,and y=10 when x=2/ Write an inverse variation equation that relates x and y. i got y=2/10x is that correct?
**
The first equation would be y=2x
The procedure for finding the inverse is to interchange x and y and solve for y:
x=2y
y=x/2 (this is the inverse of y=2x)
see the graph below as a visual check on the answer:
