9x2 - 49 =
3x2 + 17x - 6 =

$250 deductible means jane must pay the first $250 of her bill. so the insurance company paid = (80% of bill) - deductible = (0.8 x $2550) - $250 = $2040 - $250 = $1790 and jane's cost is = (bill) - (insurance payment) = $2550 - $1790 = $760

You need to do x2-x1,y2-y1 and divide it by 2 and you should get (1,-3)
