ANSWER
![y = - 2x - 5](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20-%205)
EXPLANATION
We can use any two points to determine the slope.
The line passes through;
(-3,1) and (-5,5).
The slope is given by
![m = \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20)
This implies that;
![m = \frac{5 - 1}{ - 5 - - 3}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B5%20-%201%7D%7B%20-%205%20-%20%20-%203%7D%20)
![m = \frac{4}{ - 2} = - 2](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B4%7D%7B%20-%202%7D%20%20%3D%20%20-%202)
We can now find the equation using the formula;
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
![y - 1 = - 2(x + 3)](https://tex.z-dn.net/?f=y%20%20%20-%201%20%3D%20%20-%202%28x%20%20%2B%203%29)
Expand:
![y = - 2x -6 + 1](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20-6%20%2B%201)
![y = - 2x - 5](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20-%205)
Answer: only has one solution
Step-by-step explanation: If you find the answer for 7x+3x-8, youll get 10x+8. This will be the same answer for 2(5x-4). Making them equal and having only one solution
