Question 244471: write this equation in slope-intercept form for each line according to the given information.
The line contains the point (–3, 5) and is perpendicular to the line y = 3x – 4.
y = 3x – 4
-3x -3x
____________
y = x + -7/1
--------------
y - y1 = m(x - x1)
y - (5)= -7/1 (x - -3)
-----------------------
i just showed what i believed was the correct way of doing this problem, but i am very unsure and i believe i did it wrong. can you please help me?

You can put this solution on YOUR website! write this equation in slope-intercept form for each line according to the given information.
The line contains the point (–3, 5) and is perpendicular to the line y = 3x – 4.
--------------
y = 3x - 4 is in slope-intercept form, so the slope is +3.
The slope of all lines perpendicular to it is the negative inverse, -1/3.
----------
Use y = mx + b and the point to find b.
5 = (-1/3)*(-3) + b
b = 4
------
--> y = (-1/3)x + 4
