Answer:
Yes
Step-by-step explanation:
To form a triangle : The sum of any two side lengths must be bigger than then the third side length and their difference smaller than the third side length.
19.6 + 1.6 > 18.7
19.6 - 1.6 < 18.7 and so on.

Step-by-step explanation:
The given system is :
![y = - x + 5](https://tex.z-dn.net/?f=y%20%3D%20%20-%20x%20%2B%205)
![y = \frac{1}{4}x + 10](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B1%7D%7B4%7Dx%20%2B%2010)
Let us equate both equations and solve for x.
![- x + 5 = \frac{1}{4}x + 10](https://tex.z-dn.net/?f=%20-%20x%20%2B%205%20%3D%20%20%5Cfrac%7B1%7D%7B4%7Dx%20%2B%2010)
![- 4x + 20 = x + 40](https://tex.z-dn.net/?f=%20-%204x%20%2B%2020%20%3D%20x%20%2B%2040)
![20 - 40 =x + 4x](https://tex.z-dn.net/?f=20%20-%2040%20%3Dx%20%2B%204x)
![- 20 = 5x](https://tex.z-dn.net/?f=%20-%2020%20%3D%205x)
![x = - 4](https://tex.z-dn.net/?f=x%20%3D%20%20-%204)
![y = - - 4 + 5 = 9](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20-%204%20%2B%205%20%3D%209)
The the two lines of this system will meet at (-4,9)
