The answer to the question
(y2-y1)/(x2-x1) if you have 2 points
And rise/run on graph
Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
= 36
Now find B using midpoint formula:
B: (a+b)/2
=36+0/2
=18
Answer:
Option A is correct.
Value of 
Step-by-step explanation:
Given:
and common difference(d) = 3.4
A sequence of numbers is arithmetic i.e, it increases or decreases by a constant amount each term.
The sum of the nth term of a arithmetic sequence is given by;
, where n is the number of terms, a is the first term and d is the common difference.
We also know the nth tern sequence formula which is given by ;
......[2]
First find a.
it is given that 
Put n =12 and d=3.4 in equation [2] we have;
2.4 = a + 37.4
Simplify:
a = - 35
Now, to calculate 
we use equation [1];
here, n =2 , a =-35 and d=3.4




Simplify:

Therefore, the sum of sequence of 22nd term i.e, 
There are 16 ounces in a pound
62/16 = 3 pounds 14 ounces
Hope this helps!
