B
Using pythagoras theorem
![a^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20)
![2 {a}^{2} + 2 {b}^{2} = 2 {c}^{2}](https://tex.z-dn.net/?f=2%20%7Ba%7D%5E%7B2%7D%20%20%2B%202%20%7Bb%7D%5E%7B2%7D%20%20%3D%202%20%7Bc%7D%5E%7B2%7D%20)
Therefore to find AC (which is 2c)
![2c = \sqrt{2( {a}^{2} + {b}^{2} )}](https://tex.z-dn.net/?f=2c%20%3D%20%20%5Csqrt%7B2%28%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%29%7D%20)
Hence it's B.

Answer:
5
Step-by-step explanation:
Step 1. Get two points off the graph
Points: (-70, 0) and (-60, 50)
Step 2. Use the two points to find the slope
m = slope
m = change in y/change in x
m = y2 - y1/x2 - x1
m = 50 - 0/-60 - -70
m = 50/10
m = 5/1
m = 5
The slope is 5
