Write and equation of the line described:
Contains (4,9) and is perpendicular to the graph of y = 7x + 3/8.
------------------------------
The given line has slope = 7
-------------
The line you want must have slope = -1/7
-------------
Equation form is y=mx+b and you know m,x and y; so slove for "b":
9 = (-1/7)*4 +b
9 = -4/7 + b
b = 67/7
-------------
EQuATION:
y = (-1/7)x + (67/7)
===============================
