Step-by-step explanation:

the slope is the diference in y values /diference in x values of 2 points

1.

m= 14.75 -2.75 / 5-1 = 12/4 = 3

2.

8-0/1- -3= 8/1+3=8/4= 2

i don't know gravity?

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
