Question 940062
The problem is the same as, find the equation of the line perpendicular to the one containing (0,0) and (4,-2), and passing through the midpoint of the segment connecting those two given points.


Here is an outline of what you can do:


-

Line containing (0,0) and (4,-2)
;
slope is {{{-1/2}}}, and intercepts are 0.
{{{y=-x/2}}}


Negative reciprocal of that line's slope
{{{m=2}}}


Midpoint of  endpoints  (0,0) and (4,-2)
(You do this?)


Use point-slope form to find the requested line's equation
(You do this?)
