Step-by-step Solution
To find the distance between points \( P(6,1) \) and \( Q(7,5) \), we can use the distance formula:
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Here, \( P(x_1, y_1) = (6, 1) \) and \( Q(x_2, y_2) = (7, 5) \).
Substituting the coordinates into the formula:
\[
d = \sqrt{(7 - 6)^2 + (5 - 1)^2}
\]
\[
d = \sqrt{(1)^2 + (4)^2}
\]
\[
d = \sqrt{1 + 16}
\]
\[
d = \sqrt{17}
\]
So, the distance between \( P \) and \( Q \) is \( \sqrt{17} \).
Next, to find the coordinates of the midpoint of the line segment \( PQ \), we use the midpoint formula:
\[
M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)
\]
Substituting the coordinates of points \( P \) and \( Q \):
\[
M = \left( \frac{6 + 7}{2}, \frac{1 + 5}{2} \right)
\]
\[
M = \left( \frac{13}{2}, \frac{6}{2} \right)
\]
\[
M = \left( \frac{13}{2}, 3 \right)
\]
Thus, the coordinates of the midpoint of the line segment \( PQ \) are \( \left( \frac{13}{2}, 3 \right) \).
In summary:
(a) The distance between \( P \) and \( Q \) is \( \sqrt{17} \).
(b) The coordinates of the midpoint of the line segment \( PQ \) are \( \left( \frac{13}{2}, 3 \right) \).
Quick Answer
