-1.

Explanation:

You see, slope is calculated by this formula:
y2y1x2x1

y2 is the y value of the second ordered pair (in this case, 7)
y1 is the y value of the first ordered pair (in this case, 1)
x2 is the x value of the second ordered pair (in this case, 2)
x1 is the x value of the first ordered pair (in this case, 4)

Plugging it in...
7(1)2(4)=66=1

The slope is 1.
