Answer:
S8 = 112
Step-by-step explanation:.
The question is incomplete
Assuming we are given the following
First term a =7
number of terms n = 8.
Common difference d=2
We can find the sum of the first 8terms S8
Substitute the given values
S8 = 8/2[2(7)+(8-1)(2)]
S8 =4(14+7(2))
S8=4(14+14)
S8 = 4(28)
S8 = 112
Hence the sum of the first 8terms is 112
Note that the values are assumed values

Answer:
The option A) is correct
"The lines have proportional slopes" is correct
Therefore the given slopes are proportional to each other
Step-by-step explanation:
Given that Line f has a slope of
, and line g has a slope of 
Also given that f and g are distinct lines
To check the proportionality of two slopes :



Therefore the given slopes are proportional to each other
Therefore option A) is correct
"The lines have proportional slopes" is correct
