Answer:
-2
Step-by-step explanation:
The slope of a line is given by
m = (y2-y1)/(x2-x1)
= (-3 -5)/(2- -2)
= -8/(2+2)
-8/4
-2
Answer:
Series A has an r value of 2/5 and series A has an r value of 3. The sum of the series A is 50/3
Step-by-step explanation:
A geometric sequence is in the form a, ar, ar², ar³, . . .
Where a is the first term and r is the common ratio = 
For series A: 10+4+8/5+16/25+32/125+⋯ The common ratio r is given as:

For series B: 1/5+3/5+9/5+27/5+81/5+⋯ The common ratio r is given as:

For series A a = 10, r = 2/5, which mean 0 < r < 1, the sum of the series is given as:
