What is the slope of a line perpendicular to the line containing the points $(4,-7)$ and $(-5,-1)$? Express your answer as a common fraction.
+36916 Slope between the two points = m = (-7- -1)/ (4- -5) = -6 / 9
perpindicular slope is - 1/m = 9/6
y = 9/6 x would be a perpindicular line
+36916 THen you should check the points you posted in your question, because 4/5 is incorrect ....
Here is a graph:

+36916 Nope....that is incorrect too.... look at my graph..... did you enter the points correctly ???????????
