Question

Which best describes the function on the graph?

direct variation; k = −2
direct variation; k =
inverse variation; k = −2
inverse variation; k =

Answer 1

direct variation; k = -2

Explanation:

Direct variation is a type of relationship between two variables where one variable changes in direct proportion to the other variable. This means that if one variable is multiplied by a constant, the other variable will also be multiplied by that same constant. The equation for direct variation is y = kx, where k is a constant.

In the graph, we can see that the y-value changes by -2 for every 1-unit change in the x-value. This means that the constant k in the equation y = kx is -2.

Therefore, the answer is direct variation; k = -2.
