The answer would be A.
We first would need to know the slope-intercept form (y=mx+b).
The next thing is to know what the slope is (rise/run, so from a point the rise is how far up (positive) or down (negative) it must go to get to the other point and run is how far left (negative) or right (positive) you must go to meet with the second point)
Now, with this, we can solve our question above. The slope is -2/5.
Intercept on the line is -3.
So this means we are looking for the form y=-2/5x-3... but uh, oh, none of the answers is that SO now we must change to two none slope Intercept form into it.
You can see how I did it by looking at the photo :)
