Answer: A direct variation equation can be written in the form y = kx, where k is the constant of variation.
Given the point (4, 16), we can substitute these values into the equation to solve for k.
16 = k(4)
Now, solve for k by dividing both sides by 4:
k = 16 / 4 k = 4
So, the equation of the direct variation that includes the point (4, 16) is y = 4x.
