The following set of ordered pairs represents a power inverse variation. (2,4),(1,32),(4,1/2)
what is the value of r

the kind of function they're looking for is y=k/x^r
I've gotten this far
4=k/2^2=r
but I can't figure out how to get k or r without having the other one first

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
