Question

The value of "y" varies directly with "x".
If y = 102, then x = 17.
Solve for k.

Answer 1

Given the value of x varies directly with the value of y means that x and y are proportional to each other, so y = kx.

We can easily solve for k by substituting in the given x and y values into y = kx:

y = 102

x = 17

y = kx

102 = k(17)

102/17 = k

k = 6
