Answer:

slope = 10

Explanation:

Examination of the values shows you that each y-value is 10 times the corresponding x value. That means the slope is 10. (If the ratios were different, then the slope formula would need to be used. The fact that they are all the same means y is proportional to x.)

__

You can use the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (40 -20)/(4 -2) = 20/2

m = 10

The slope is 10.
