<PRE><B>Question 285404</B>
write an equation of the line containing the given point and perpendicular to the given line, Express your answer in the form y=mx+b
(3,7);7x+y=8
------------------------
Find the slope of the given line:
y = -7x+8
slope = -7
--------------------
The slope of any line perpendicular to the
given line is 1/7
-------------------------
Find Equation of line with slope = 1/7 and passing thru (3,7)
---
7 = (1/7)3 + b
49/7 = 3/7 + b
b = 46/7
-------------------
Equation: 
y = (1/7)x+(46/7)
