Answer:
The slope of a line perpendicular to m=2 is m= 1.
Explanation:
2x+2y=-12
2y=-2x-12
y= -x-6.
The equation is in slope-intercept form now, so it is easy to tell what the slope is.
The slope of y= -x-6 is m = -x. Technically, -x = -1x, so now make the -1 positive and find the reciprocal, which is still 1.
All you need to do to find the perpendicular slope of any line is simply to find the reciprocal of the number and make the positive/negative number the opposite. I hope this helps, have a good day/night! :)
