To find the length of segment AC, we must find the total rise and total run between the two points.
Point C is located at (-5, 5). Point A is located at (3,-1). To find the rise, subtract the y-value of A from the y-value of C:
![5 - (-1) = 6](https://img.qammunity.org/2019/formulas/mathematics/middle-school/w4sbnb9e0fwjwum1psy9hyyct8n17x1iuz.png)
The rise of this segment is 6.
To find the run, subtract the x-value of A from the x-value of C:
![3 - (-5) = 8](https://img.qammunity.org/2019/formulas/mathematics/middle-school/zjoc3zgk5sax9plxudwdzbdyfdusnx6of9.png)
The run of this segment is 8.
We can use the Pythagorean Theorem to find the length of this segment. The theorem uses the following formula:
![a^(2) + b^(2) = c^(2)](https://img.qammunity.org/2019/formulas/mathematics/college/3byu32yniwf4k67ty0w3p5iut2e0wsjpqf.png)
The segment represents the hypotenuse, and the rise and run represent the legs of this segment. We know that the two legs' lengths are 6 and 8, so plug them into the equation:
![6^(2) + 8^(2) = c^(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/wa5ef9m44u2redjwe1uqtyaznr9d5lv14g.png)
![36 + 64 = c^(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/lv9wkqmgxwtpxix96hwf6ksu08e124dknp.png)
![100 = c^(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/p1q1rxfbfxptb2yf34jy9b3jxk675a2exm.png)
Square root both sides to get c by itself:
![√(100) = 10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nrp2qoiercgnmjowmqg80756gd9vdz64mx.png)
![c = 10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/lmcg507bnuibg57pvmtw6nbh366tz6fool.png)
The length of segment AC is
10.
