Question 56188
Find the slope of any line perpendicular to the line through points (6, 3) and (7, 7).
The slope formula is:{{{highlight(m=(y2-y1)/(x2-x1))}}}
(x1,y1)=(6,3) and (x2,y2)=(7,7)
{{{m=(7-3)/(7-6)}}}
{{{m=4/1}}}
A slope of any line perpendicular to this slope is the negative reciprocal of this slope, so change the sign and flip it over.
{{{highlight(m=-1/4)}}}
Happy Calculating!!!
