Answer:
y=-1/12x+11/3
Step-by-step explanation:
When a line is perpendicular, the slope is going to be the negative reciprocal
negative reciprocal ex: 3----> -1/3
since the slope of line you are given is 12, the slope of the perpendicular line is -1/12
so you now know your equation so far is y= -1/12x+b
to find b, replace x and y with the coordinates.
4= -1/12(-4)+b
4=1/3+b
11/3=b
the equation is y=-1/12x+11/3
