<PRE><B>Question 1148569</B>
x +2y = 12
:
rewrite the line&#39;s equation in slope y-intercept form
:
y = -x/2 +6
:
slope of the line is -1/2
:
the slope of the line perpendicular to our line is the negative reciprocol 
:
slope is -(1/(-1/2)) = 2
:
using the slope y-intercept form
:
y = 2x +b
:
now subsitute the x coordinate for x and the y coordinate for y using the given point
:
-4 = 2(2) +b
:
b = -8
:
y = 2x -8
:
the general form is
:
2x -y = 8
