<span>Well First you multiply 67 kg, which is how much parker weighs, by 30. 30ml/kg means that there is 30ml for ever 1 kg and parker weighs 67. So Parker needs 2010 ml of fluid and the last thing you need to do is convert 2010 ml into cups. 1ml =.00423 cups. So you multiply 2010 by .00423 and you'd have you're answer.

The answer has to resemble y=Mx+b so to find your y intercept plug in your coordinates into that equation so put your slope in for m and your x intercept in for x and the y intercept in for y so -4= -3(-1)+b now get b alone -1=b so your equation would be y=-3x-1
