Hello,
1) We must find the equation of the line RS:
R=(-1;6)S=(5;5)
y-6=(x+1)(5-6)/(5+1)y=-1/6*(x+1)+6
y=-x/6+35/6 Slope=-1/6
The perpendicular has the slope 6.
2) Find M the middle of [RS]M=((5-1)/2;(6+5)/2)=(2:11/2)
3) Equation of the perpendicular bisector:
y-11/2=(x-2)*6y=6x-12+11/2
So y=6x-13/2
And sorry for my poor english
3)
The difference 96 -80 = 16 is a factor of both numbers, so is the greatest common factor.
96 + 80 = 16*(6 + 5)
