wait this depends wether emily and zach how they are thinking.
yes they are the same.
i know the point slope is y= 1/11x-46/11
secant-secant formula:
(whole secant) x (external part) = (whole secant) x (external part)
(8+y-2) *8= (y+4+6) *6
(y+6)*8 = (y+10) *6
distribute
8y+48 = 6y +60
subtract 6y from each side
2y +48 = 60
subtract 48 from each side
2y = 12
divide by 2
y = 6
sv = (y+4+6)
sv = 6+4+6
sv = 16
