Question 1191010
Find the equation of the line passing through the point (6,3) that is perpendicular to the line 4x−5y=−10
-----------------
Step 1, find the slope of the given line, call it m1.
---
The slope of lines perpendicular is the negative inverse of m1, which is -1/m1.  Call that m.
-----
Step 2, use y-y1 = m*(x-x1) where (x1,y1) is the point (6,3)
