<h3>Answer:</h3>
2/15
<h3>Explanation:</h3>
There are 8C2 = 28 ways to choose 2 dimes from the 8 dimes in Annie's purse. There are 21C2 = 210 ways to choose 2 coins from the 21 coins in Annie's purse.
Of the 210 ways to choose 2 coins, 28 of the choices will result in 2 dimes being chosen. The probability of choosing 2 dimes is 28/210 = 2/15.

<em>Comment on nCk</em>
The number of ways to choose k objects from n, when order does not matter, is ...
... n!/(k!(n -k)!)
For the computations above, we have ...
... 8C2 = 8·7/(2·1) = 28
... 21C2 = 21·20/(2·1) = 210
Using proportions, it is found that the coordinates of point P are given as follows: (2,10).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The segment is partitioned by point P according to the ratio of 3:4, hence:
This proportion is applied for both coordinates, hence, for the x-coordinate:
x - 2 = 0
x = 2.
For the y-coordinate:
y - 4 = 6
y = 10.
Hence the coordinates are (2,10).

I hope this helped. Not 100% sure what you were looking for, though.
Answer:
y=10x−18
Step 1: Flip the equation.
10x−18=y
Step 2: Add 18 to both sides.
10x−18+18=y+18
10x=y+18
Step 3: Divide both sides by 10.
10x
/10 = y +18/10
