Write an equation of the line that is perpendicular to 5x + 20y = 10 and passes through the point (8, 3)
--------
Find the slope of the given line:
5x + 20y = 10
y = (-1/4)x + (1/2)
---
slope = -1/4
-----------------------
Therefore slope of the perpendicular line must be 4
---------
Form: y = mx + b
You have y = 3 when x = 8 , and m = 4
Solve for "b":
3 = 4*8 + b
b = 29
----
Equation:
y = 4x + 29
