All of my teachers have told me that everyone remembers things best in groups of seven. so I would suggest to pick a continent and start in a corner and spend a couple of days studying seven countries in that area. also quiz your self every once in a while for extra help.
I hope this helps you
Point A ( -1/2,1/4)
Point B (-2 1/2,-1 1/2)
Point C (1/2,1/4)
If you have information about 5 servings, assuming that all servings have the same calories, the information about one serving is simply obtained by dividing the total by 5.
So, each serving has

calories
Answer:
slope = - 
Step-by-step explanation:
the slope of the secant line in the closed interval [a, b ] is
slope = 
here [a, b ] = [1, 4 ]
f(b) = f(4) = -
+ 5 = - 16 + 5 = - 11
f(a) = f(1) = -
+ 5 = - 2 + 5 = 3
slope =
=
= -
