Question

Write an inverse variation equation that relates x and y if y= 6 when x= -3 then find y when x= -9​

Answer 1

Answer: 2

Explanation:

Function inversely proportional:

y = k/x

Solve for k from the point they gave you on the line y=6 and x=-3

6 = k/(-3) >multiply -3 to both sides

-18 = k >This is your k value

y = -18/x >This is your generic equation of the line

Now they want to know what is y when x= -9

y= -18 / -9

y = 2
