Answer:
![\frac{2}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B7%7D)
Step-by-step explanation:
In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.
In this case we were already given the points for slope:
![P1=(-4,-4) = (x1,y1)](https://tex.z-dn.net/?f=P1%3D%28-4%2C-4%29%20%3D%20%28x1%2Cy1%29)
![P2=(-2,3)=(x2,y2)](https://tex.z-dn.net/?f=P2%3D%28-2%2C3%29%3D%28x2%2Cy2%29)
Slope formula:
![slope = \frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=slope%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
Now substitute:
![\frac{-2--4}{3--4}](https://tex.z-dn.net/?f=%5Cfrac%7B-2--4%7D%7B3--4%7D)
Solve using KCC: (Keep, Change, Change)
![-2+4=2](https://tex.z-dn.net/?f=-2%2B4%3D2)
![3+4=7](https://tex.z-dn.net/?f=3%2B4%3D7)
=![\frac{2}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B7%7D)
Because the slope isn't a negative you do not need to simplify the answer.
Hope this helps.
The answer is C
explanation
Yes ABD=CBD since they both are just half of the triangle
