It's easiest to start with the point-slope form of an equation, 
, where m is the slope and 
is the point given.
We have m = 3,
, and 
.
We plug in these values to get
.
We now rearrange to get this into slope-intercept form,
, by solving for y.
We have m = 3,

Answer:
The work will be finished in 10 days.
Step-by-step explanation:
Rashid can do a piece of work in 8 days
This means that each day he works, Rashid does of the work.
Tipu can finish in 12 days.
This means that each day he works, Tipu does of the work.
Each 2 days:
Each 2 days they work, the amount done is given by:
Each 2 days, 5/24 of the work is done:
The number of periods of 2 days that is needed to finish the work(100% = 1 completed), is given by:
2*4.8 = 9.6
Rounding up
The work will be finished in 10 days.
