a triangle has vertices p(1, 3), q(3, 5), and r(6, 2).
the slope of the median to qr is
a. 1/7
b -1/2
c. 1

The answer is a. 1/7
The length of QR is 3 sqrt(2) which means half of that is where the median intersects. Since the triangle formed is a right triangle with legs that are equal. The vertex angles are 45°, we can get the coordinates of the point of intersection which is (4.5,3.5).
So, 
m (slope) = (3.5-3)/(4.5-1) = 1/7

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
