We can choose any two points on the line and find the slope using the slope formula:

slope = (change in y)/(change in x)

Let's choose two arbitrary points: (0,0) and (1,9).

Using these points, we can find the change in y:

y2 - y1 = 9 - 0 = 9

And the change in x:

x2 - x1 = 1 - 0 = 1

Therefore, the slope is:

slope = (change in y)/(change in x) = 9/1 = 9

So the answer is B) 9.
