SOLUTION: "Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the graph of the line." (-1,4),y=3x+5 I have already done h

Question 1128467: "Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the graph of the line."

(-1,4),y=3x+5
I have already done half of the problem the first equation is y=-4x correct me if I'm wrong. I just don't understand the second part of the question. Can you help me out? Please and thank you.

Given equation is of slope 3.
Line PERPENDICULAR to it will have slope .

Solve for b, and substitute x=-1,and,y=4 to find the value for b.
