Answer:
The common difference of given AP is Option 2) -10.
Step-by-step explanation:
We are given the following information in the question:
First term of AP, a = 100
The sum of its first 6 terms = 5(the sum of its next six terms)
We have to find the common difference of AP.
The sum of n terms of AP is given by:
where a is the first term and d is the common difference.
Thus, we can write:
Thus, the common difference of given AP is -10.

Answer:
slope-intercept form equation: y = x + 5
Step-by-step explanation:
you take the 2 y's, 18 and -13, then you subtract them: 18 - (-13) = 31
then you take the 2 x's, 13 and -18, subtract them too: 13 - (-18) = 31
divide those 2 sums: 31/31 = 1
so the slope is 1
then when you graph it you get an y-intercept of 5
so the equation is y = x + 5
hope this helps :)
