Tell whether x and y show direct variation, inverse variation, or neither: y = 2/x

• direct variation
• inverse variation
• compound variation
• neither

The point (-14, -8) lies on the graph that depicts direct variation Find the value of y so that the point(7, y)        lies on the same graph. 

Just type the number. Do not type y =
