Question

Variables x and y are in direct proportion, and y = 48n when x = 16n. Which value of k correctly relates x and y in the equation y = kx?

Answer 1

Y = kx is the direct variation formula. They are giving y = 48n AFTER they have plugged in a value for x. The value plugged in for x is 16n. To find 'k' we must divide 48n by 16n.
48n/16n = 3 So k = 3.
The equation is therefore y = 3x
