Notice as x increases, y increases, so the slope must be positive... you can eliminate options c and d since each have a negative slope.

You may want to plot the points, then draw the other two lines in, and see which is the best fit. It's gonna be difficult to decide otherwise.

agent0smith · Answer

Yeah, that's why you'll need to plot the points I think.
