Suppose y varies inversely with x. Write an equation if y=-3 when x=17

y = - 51 : x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k : x. The question asks us to write an equation if y = - 3 when x = 17 and y varies inversely with x.

So we substitute the values y = - 3 and x = 17 in the equation y = k : x

K = constant, we have to work this out

-3 = k : 17

-3 * 17 = k

k = - 3 * 17

k = - 51

k = - 51 So then we put this back into the original y = k : x to find our final equation which is y = - 51 : x
