Paco signed up for a gym membership 17 weeks after marlon

let ‘a’ represent the number of weeks paco has been a member and ‘b’ the number of weeks marlon has been a member

find the value of ‘b’ when ‘a’ = 3

Here  b = -14

Step-by-step explanation:

The number of weeks Paco has been a member : a

The number of weeks Marlon has been a member : b

Now, according to the question

b + 17  = a

Now, here given a = 3

So, b + 17  = 3   or,    b = 3 -17 = -14

    ⇒ b = -14

i would need to see the dot plot : )
