Question 911879
Find the equation of the line through the given point and perpendicular to the given line.
(0,0);-2x+4y=12
---------------------
Given line -2x+4y = 12, find the slope::
4y = 2x + 12
y = (1/2)x + 3
slope = 1/2
----
Slope you want must be -2.
----
Form:: y = mx + b
Solve for "b" by substitution::
0 = (-2)*0 + b
b = 0
--------------
Ans:  y = -2x
