For the points you've given, the correct answer is not listed! One way to solve the problem is just to use a graph -- the points are not far away from the origin, and they have whole number coordinates. (See graph.)

Slopt = "rise" / "run" so to get from (2, 2) to (4, 3), you "rise" +1 and "run" +2. The slope is 1/2.

If the points are (2, 2) and (4, 3), then the slope would be 2.

You can always use a formula to find the slope:


m=(y_2-y_1)/(x_2-x_1) which tells the slope of a line joining points
(x_1,y_1) and
(x_2,y_2).

The formula says

Slope = (second y minus first y) / (second x minus first x)

It always works unless
x_1=x_2, in which case the line is vertical and has NO defined slope.
