It is 1 over 8 aka 1/8. hope it helped.
For slope-intercept form is y=mx+b
Therefore the answer should be:
y=-4x+7
The Y values are the same, so the Y value for A would also be 3.
B is at x 0 and the midpoint is -4 so there are 4 units between the mid point and B. You need to subtract 4 units from the midpoint for A.
-4 - 4 = -8
Point A is located at (-8,3)
