The midpoint is (5, ¹/₂).

<h3>Further explanation</h3>

The midpoint is the coordinates of a point right in the middle of a line segment or two endpoints.

The Midpoint Formula $\boxed{\boxed{ \ M = \bigg( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \bigg) \ }}$

So, abscissa and ordinate of the midpoint are the averages of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).

Given (x₁, y₁) = (5, 4) and (x₂, y₂) = (5, -3).

Let's calculate the midpoint.

$\boxed{ \ M = \bigg( \frac{5 + 5}{2}, \frac{4 + (-3)}{2} \bigg) \ }$

$\boxed{ \ M = \bigg( \frac{10}{2}, \frac{1}{2} \bigg) \ }$

$\boxed{ \ M = \bigg( 5, \frac{1}{2} \bigg) \ }$

We get the midpoint between the two endpoints, that is, (5, ¹ / ₂).
