If we have two coordinates that are in the line we can find the slope with this equation:

So now we replace the coordinates so:

Now with the slope and any point we can find the intercept in the y axis by replacing x=0 so:

So the equation is:
I will find comission
7% of 210000
percent means parts out of 100
7%=7/100
7/100 times 210000=1470000/100=14700
comission is $147000
The length of the shortest piece is 5cm.
Given that the length of the board = 62cm
Let the length of the first piece be x cm.
Hence, according to the question,
Length of the second piece = 2x cm
Length of the third piece = (2x + 7) cm
We have to find the length of the shortest piece.
Hence, we can write,
62 = x + 2x + (2x + 7)
62 = 5x + 7
5x = 62 - 7 =55
x = 55/11 = 5 cm
Hence, the shortest side is the first side of 5 cm.
