The slope of this line is (5- -4) / (0- -3) = 9/3 = 3
Lines that are perpendicular have slopes that are opposite signs AND reciprocals. Therefore, the slope of perpendicular to a slope of 3 is -1/3

The slope of the line L through (0,5) and (-3,-4) is
(y_2-y_1)/(x_2-x_1)= -9/-3 = 3
The slope of a line perpendicular to L is the
negative reciprocal of 3 or -1/3.

slope formula:
m = (y2 - y1) / (x2 - x1)
m = (-4 - 5) / (-3 - 0)
m = -9 / -3
m = 3
perpendicular means negative recipricol:
m = -1/3
