Math club needs to choose for people for committee to represent at a board school meeting the club consists of fourteen members 9 girls and five boys

You can only ask one question per post.  I will do question number 1.  If segment AB is divided into a ratio of 2:3, that means point M is found 2/5s of the way down the segment AB (starting from point A).

So if the change in the x-direction from point A to point B +20, then point M is found 2/5 of 20 away from point A, which is 8.  So x-value of point M is 8.

And if the change in the y-direction from point A to point B is -15, then point M is found 2/5 of -15 away from point A, which is -6.  So -6 from 15 is the y-value of 9.  So the y-value of point M is 9.

So point M is (8,9).   The answer is A.
