Three friends - Jim, Steve, and Bernie live on the same side of a street Steve's house is halfway between Jim's and Bernie's houses. If the locations or Jim's and Bernie's houses can be given by the coordinates (2,5) and (4.17) what coordinates represent the location of Steve's house?
(2.12)

is this the complete

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
