6/8+1/8 equals to seven eighth. Don't forget to choose my answer as the brainiest one if it was useful. Thanks
Answer:
A.
Step-by-step explanation:
We are given the two points (2,7) and (4,-1). In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:
![m=\frac{y_2-y_1}{x_2-x_1} =\frac{-1-7}{4-2}=-8/2=-4](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%3D%5Cfrac%7B-1-7%7D%7B4-2%7D%3D-8%2F2%3D-4)
Thus, the slope is -4.
Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Where (x1, y1) is a coordinate pair and m is the slope.
Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively:
![y-(7)=-4(x-(2))\\y-7=-4x+8\\y=-4x+15](https://tex.z-dn.net/?f=y-%287%29%3D-4%28x-%282%29%29%5C%5Cy-7%3D-4x%2B8%5C%5Cy%3D-4x%2B15)
This is also slope-intercept form. The answer is A.

Answer:
Either 2358.5 feet or 0.4 miles (see explanation)
Step-by-step explanation:
using the formula of pythagorean theorem (a squared = b squared plus c squared), the route your friend takes would be 2358.5 feet. Converting that to miles would be 0.4 miles
