Explanation:
1. just count the units: 5 units
2. Find the slope = rise/run = -7/6
you now have a right triangle, one side is 7 units (from the rise), and the other is 6 units (from the run)
use the pythagorean theorem to find the hypotenuse.
![a^(2) +b^(2) =c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/k7qt5wkjzyq5o063duwhj1rojahhnrxc3q.png)
![7^(2) + 6^(2) = c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/ec1s53rsr3thpzs61oa02edgxoo9fi5h59.png)

![√(85) = \sqrt{ c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/m7rlir3581sbyupobj4574r38aaroimn15.png)
![√(85) = c](https://img.qammunity.org/2022/formulas/mathematics/high-school/ar9i3kb39bttc0ohwwy0bgp898bowv8lax.png)
Simplify the radical, but
is farthest that it can go, so that is the answer.
3. same process as 2
slope = -1/5
![1^(2) + 5^(2) = c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/gwa8d1be44skzqypv2l0ugz9y4ksztkwgb.png)
1 + 25 =
![c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/o3ay9zmp6x77qub2fswpttcs1llic9nycf.png)
26 =
![c^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/o3ay9zmp6x77qub2fswpttcs1llic9nycf.png)
![√(26) = c](https://img.qammunity.org/2022/formulas/mathematics/high-school/6bxgh5zk1d16oownylkrqrz6boyrc5p3iz.png)
That is the farthest it can go, so that will be the answer.
