Answer:
y=(1)/(4) x-5

Explanation:

Lines perpendicular to another line have inversely proportional slopes. We are given that the slope of the line is -4, so the slope of the perpendicular line will be positive 1/4. Now we have a starting point for this line:


y=(1)/(4) x+b\\-8=(1)/(4) (-12)+b\\-8=-3+b\\b=-5

Notice how I plugged in the points given.
