Write an equation for a line passage through the midpoint A(-7,2) B(1,-6) perpendicular to line AB
I might've wrote this question wrong
Thank you for the opportunity to help you with your question!
Midpoint of A(-7,2) and B(1.-6) is ((-7+1)/2,(-6+2)/2) or (-3,-2)
slope of the line passing points A & B is m; where m=(-6-2)/(1+7)=-8/8=-1
slope of perpendicular the line is n; where n=-1/m=1
Thus equation of line passing through midpoint (-3,-2) with slope n=1 is:
Therefore,a line passage through the midpoint A(-7,2) B(1,-6) perpendicular to line AB
