You can put this solution on YOUR website! 2x+y+4=0
find the equation of the line perpendicular to 2x+y+4=0 passing through the points 5,3 give your answer in the form ax+by+c=0
-----------
Find the slope of 2x+y+4=0
-----------
The slope of lines perpendicular to it are the negative inverse of its slope.
----
Use y = mx + b to find the equation, or
use
y - y1 = m*(x - x1) where (x1,y1) is the point (5,3)
-----------
PS Put poing in parentheses.
