Answer:
![y-6 = -\frac{1}{2} (x+1)](https://tex.z-dn.net/?f=%20y-6%20%3D%20-%5Cfrac%7B1%7D%7B2%7D%20%28x%2B1%29)
Step-by-step explanation:
For this case we have two points given (-1,6) and (1,5)
And we want to complete the point slope equation of the line:
![y-6 = m(x-x_o)](https://tex.z-dn.net/?f=%20y-6%20%3D%20m%28x-x_o%29%20)
We need to find the slope and we can use the following formula:
![m = \frac{y_2 -y_1}{x_2 -x_1}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D)
And replacing the info we got:
![m= \frac{5-6}{1-(-1)}=-\frac{1}{2}](https://tex.z-dn.net/?f=%20m%3D%20%5Cfrac%7B5-6%7D%7B1-%28-1%29%7D%3D-%5Cfrac%7B1%7D%7B2%7D)
And then the equation would be given by:
![y-6 = -\frac{1}{2} (x- (-1))](https://tex.z-dn.net/?f=%20y-6%20%3D%20-%5Cfrac%7B1%7D%7B2%7D%20%28x-%20%28-1%29%29)
And our final answer would be:
![y-6 = -\frac{1}{2} (x+1)](https://tex.z-dn.net/?f=%20y-6%20%3D%20-%5Cfrac%7B1%7D%7B2%7D%20%28x%2B1%29)

According to the proper order of operations ('PEMDAS'),
multiplication is done before addition/subtraction.
So the (40 x 0) in the middle is done first, and goes away.
Then you're left with 40 + 0 + 1 = <em>41</em>.
