Answer:
20 unique words
Step-by-step explanation:
mommy is a 5 letter word. So initially we would think there are 5! = 120 words to spell from here. however, If we are looking for unique solutions, we need to consider that there are 3 m's. the multinomial theorem says that we should divide by each group of duplicates so 5!/(3!1!1!) = 5!/3! = 20 unique words
The given equation is in point-slope form.
The general form of an equation in point slope form is:
![y- y_{1}=m(x- x_{1})](https://tex.z-dn.net/?f=y-%20y_%7B1%7D%3Dm%28x-%20x_%7B1%7D%29%20%20)
Here m is the slope and
![x_{1}](https://tex.z-dn.net/?f=%20x_%7B1%7D%20)
and
![y_{1}](https://tex.z-dn.net/?f=%20y_%7B1%7D%20)
are the coordinates of the point.
So in given equation the slope is 2/3, and the coordinates of point are (1,3)
