Segment $s_1$ has endpoints at $(1,2)$ and $(7,10)$. Segment $s_2$ is obtained by translating $s_1$ by $3$ units to the right and $2$ units down. Find the midpoint of segment $s_2$. Express your answer as $(a,b)$ with $a$ and $b$ integers.
The endpoints of s2 are 3 to the right and 2 down from the endpoints of s1
s1 has endpoints at (1, 2) and (7, 10)
s2 has endpoints at (1 + 3, 2 - 2) and (7 + 3, 10 - 2)
s2 has endpoints at (4, 0) and (10, 8)

midpoint of s2 = \(\Big( \frac{4+10}{2},\frac{0+8}{2} \Big)\ =\ \Big(\frac{14}{2},\frac82\Big)\) = (7, 4)
