The slope of perpendicular to the line through points (0,5)and(-3,-4).
slope = -4-5/-3-0
= -9/-3
= 3
But, it is perpendicular. It means -1/3
So, the slope is -1/3

For the line whose data set contains the points (0,5) and (-3,-4), the slope is 3. Therefore, to calculate the slope of the line perpendicular to it, one must take the reciprocal of the former line's slope and change the sign. Thus, the slope of the line perpendicular to the former line is -1/3.

Well you find the slope by finding the change in y divided by the change in x. Then take the negative reciprocal of the slope.
slope = (Y2-Y1)/(X2-X1)
= (-4- (5))/((-3)-0)
=- 9/-3
= 3
Then take the negative reciprocal.
-1/3

Slope=
Y2-Y1
--------
X2-X1
(X1,Y1)
(0,5)
(X2,Y2)
(-3,-4)
So...
-4-5 (Two negatives equal a positive = -4+-5)
--------
-3-0 (Two negatives equal a positive = -3+0)
-9

-3
