Find the distance from the point [11, -10, 17] to the plane

-4478 - 283 x + 347 y + 416 z = 0

and assign your exact answer to the name TheDistance.

what i did was i multipled the variables in the plane by their corresponding variables in the point, and then divided that answer by the distance or magnitude of the plane. I got 611.1906 but the computer keep saying that this is not the correct value. Anyone has an alternative solution? Thanks.
