Hey there!
First, we'll need to isolate the y variable, meaning that we'll need all of the y's on one side. To do this, we'll need to subtract 8x from both sides. This leaves us with 2y = -8x - 10.
Second, we'll need to get y all by itself, without the 2. To do this, we'll need to divide both sides by 2. This leaves us with y = -4x - 5.
Therefore, your answer is the first option, or the darkest blue box.
Hope this helps!! :)
