Find a vector perpendicular ( = normal) to the line 2y = 5-3x in the xy-plane.
Answered by oobleck
the line has slope -3/2
So, what is a vector with slope 2/3 ?

2i-3j
Did you divded by 2?-->(5-3x)/2 -->y=5/2-3x/2-->m=-3/2 right? How does the slope -3/2 become 2/3?
Answered by oobleck
if two lines are perpendicular, their slopes are negative reciprocals.
