Answer:
Look at the relationship.
2.7 is 30 times larger than 0.09 (2.7 / 0.09 = 30)
So the ratio is 0.09:2.7 = 1 :30
Step-by-step explanation:
Given that the formula of gradient is :
![m = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
So you have to try for every coordinates :
Option A,
![\frac{6-(-2)}{-1-4} = - \frac{8}{5} (incorrect)](https://tex.z-dn.net/?f=%20%5Cfrac%7B6-%28-2%29%7D%7B-1-4%7D%20%3D%20-%20%5Cfrac%7B8%7D%7B5%7D%20%28incorrect%29%20)
Option B,
![\frac{8-(-2)}{-1-4} = -2 (correct)](https://tex.z-dn.net/?f=%20%5Cfrac%7B8-%28-2%29%7D%7B-1-4%7D%20%3D%20-2%20%28correct%29%20)
Option C,
![\frac{10-(-2)}{-1-4} = - \frac{12}{5} (incorrect)](https://tex.z-dn.net/?f=%20%5Cfrac%7B10-%28-2%29%7D%7B-1-4%7D%20%3D%20-%20%5Cfrac%7B12%7D%7B5%7D%20%28incorrect%29%20)
Option D,
![\frac{12-(-2)}{-1-4} = - \frac{14}{5} (incorrect)](https://tex.z-dn.net/?f=%20%5Cfrac%7B12-%28-2%29%7D%7B-1-4%7D%20%3D%20-%20%5Cfrac%7B14%7D%7B5%7D%20%28incorrect%29%20)
Answer:
3(x/4) - 1/2 (x/10) or you can just do 0.7x but I don't think that counts as an expression, so just put 3(x/4) - 1/2 (x/10).
