<PRE><B>Question 364979</B>
Write an equation in slope intercept form for the line that passes through (5,-4) and is perpendicular to the line decribed by 2x-10y=0 
----
Slope of the given line = ?
10y = 2x
y = (1/5)x
----
Line perpendicular to it must have slope = -5
---
Find equation with slope = -5 passing thru (5,-4)5
----
Form: y = mx + b
-4 = -5(5)+b
-4 + 25 = b
b = 21
-----
Ans: y = -5x+21
