We can check each of these using the Pythagorean Theorem,

Option A:

.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B

1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:

36 + 64 = 100
100 = 100
This option works
Option D:

9 + 16 = 25
25 = 25
This option works
So, after doing the calculations, we see that option B does not work
Answer: Slope=1
You can find slope by using the 'rise over run' method. Count the number of units along the x axis, and up the y axis. As I can see, I think it is labeled as 4,4. So put the numbers into y/x (4/4) and then simplify as needed. In this case (If I can see correctly) then the slope is 1.
