B) y=12x
Step-by-step explanation:
We are given with the coordinates 
Where
represents the number of days.
represents the number of likes she got.

Let us say
and 
Slope
formula , 
Plug in the above points now, we get

Now we use the point-slope formula, 
Plugging the corresponding values.

Thus option is B is the correct answer.
The answer is 18+(-20) because if if you were going to solve that equation you would use the absolute value of -20 and then the opposite of the sign giving you 18-20. Hope this helps:)
