Pls help, complete the table will choose brainliest.

Step-by-step explanation:

So at the start:

     Percent of Narrow Shell = 348/928 = 0.375 -->   0.375* 100 = 37.5%

     Percent of Round Shell = 580/928 = 0.625 -->   0.625*100= 62.5%

At the end

     Percent of Narrow Shell = 564/800 = 0.705--> 0.705*100 = 70.5%

     Percent of Round Shell = 236/800 = 0.295-->  0.295*100 = 29.5%

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
