Answer:
The slope of the median to QR is 1/7
Step-by-step explanation:
A triangle has vertices P(1, 3), Q(3, 5), and R(6, 2).
To find the slope of the median to QR is
Mid point of QR is [tex](\frac{x1+x2}{2} , \frac{y1+y2}{2})[/tex]
Q(3, 5), and R(6, 2)
[tex](\frac{3+6}{2} , \frac{5+2}{2})[/tex]
[tex](\frac{9}{2} , \frac{7}{2})[/tex]
Now we find the slope using mid point (9/2, 7/2) and vertex (1,3)
slope = [tex]\frac{y2-y1}{x2-x1} =\frac{3-\frac{7}{2}}{1-\frac{9}{2}} =\frac{1}{7}[/tex]
