Question

describe the reflection that maps $overline{st}$, with vertices $s(-7, 1)$ and $t(-7, 5)$, onto itself. use decimals, if necessary. reflection in the line y =

Explanation:

Step1: Find the mid - point of the y - coordinates

The y - coordinates of the endpoints are $y_1 = 1$ and $y_2 = 5$. The formula for the mid - point of two numbers $a$ and $b$ is $\frac{a + b}{2}$.
So, $\frac{1+5}{2}$.

Step2: Calculate the value

$\frac{1 + 5}{2}=\frac{6}{2}=3$.

Answer:

$3$
