Question

what is the coordinate of the midpoint of st? write your answer as an integer or a decimal, or mixed number in simplest form.

Explanation:

Step1: Identify the coordinates

Let the coordinate of $S=- 5$ and the coordinate of $T = 10$.

Step2: Use mid - point formula

The mid - point formula for two points on a number line is $\frac{x_1 + x_2}{2}$, where $x_1$ and $x_2$ are the coordinates of the two points. Here, $x_1=-5$ and $x_2 = 10$. So, $\frac{-5 + 10}{2}$.

Step3: Calculate the result

$\frac{-5+10}{2}=\frac{5}{2}=2.5$

Answer:

$2.5$
