Answer 1

Answer:

  -6/7

Step-by-step explanation:

The slope of the line perpendicular to DE is the negative reciprocal of the slope of DE. The slope of DE is ...

 (change in y)/(change in x) = (y2 -y1)/(x2 -x1) = (-3-4)/(1-7) = -7/-6 = 7/6

The inverse of that is 6/7, and the opposite of that inverse is -6/7.

The slope of the line perpendicular to DE is -6/7.
