A scientist teacher 19 pints
of Lake water for a lab she is teaching. The labs requires each student to use 4 fluid ounces of water. If 56 oz of participating how many pints are make water will the teacher have left over?

Answer for the question is A the reason why is a because there either one way you can solve one is graph and the other using the midpoint formula
so what did is
(x1+x2) divide 2 (y1+y2) dived by 2
I plug in (-2+3) divide by 2 so reason y I got -2 because -2 is x1 and 3 is x2 and then I got (2-1) over 2 and once I dive (-2+3) is 1 and don't forget -2 because most people forget them and for second I did 2-1 which one so there both 1/2 I recommend grabh because there more easier so sorry this confused
