Question 124046: The problem reads:
Write the standard form of the equation of the line passing through the point (2,-4) and perpendicular to the line y= -3/7x-2
I have tried to use point-slope form, but it isn't right.
Please help me with this problem.

Write the standard form of the equation of the line passing through the point (2,-4) and perpendicular to the line y= -3/7x-2
------------------
The given line has slope -3/7 so the perpendicular line must have slope = 7/3
-------------------
Your line has form y = mx+b and you know y,x, and m; so solve for b.
---------------
-4=(7/3)2 + b
-4=14/3 + b
-12/3 = 14/3 + b
b = -26/3
----------------
EQUATION:
y = (7/3)x - (26/3)
======================
