Question

If y varies directly with x, and y is 17 when x is -30, which of the following represents this situation?

a) y = 17x
b) y = -30x
c) y = 17/x
d) y = -17/x

Answer 1

The equation that represents this situation is y = -17/30x.

Step-by-step explanation:

The given situation can be represented by the equation y = kx, where k is the constant of variation. To find the value of k, we can use the given information. When x is -30, y is 17. Substituting these values into the equation, we get 17 = k(-30). Solving for k, we find k = -17/30. Therefore, the equation that represents this situation is y = -17/30x.
