Question 86596
The solution is to find the negative reciprocal.

----Step#1: find slop of line through points (0,5) and (-3,-4)
1st:  plot points (0,5) and (-3,-4).  You will notice that the line moves up from (-3,-4) to (0,5)
2nd: Slope = Rise/Run = (5-(-4)) / (0-(-3)) = 9/3 = 3

----Step#2:  find the negative reciprocal.
Negative reciprocal = -1/3
