Question

Point L is located at (4, -3) and M is located at (-8, 5). Find the y value of the point that lies halfway between L and M.

1) 1.5

2) 4

3) 3.5

4) 1

Answer 1

\(\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
L&({\color{red}{ 4}}\quad ,&{\color{blue}{ -3}})\quad M&({\color{red}{ -8}}\quad ,&{\color{blue}{ 5}})
\end{array}\qquad
\left(\cfrac{{\color{red}{ x_2}} + {\color{red}{ x_1}}}{2}\quad ,\quad \cfrac{{\color{blue}{ y_2}} + {\color{blue}{ y_1}}}{2} \right)\)

you're only asked for the "y" value or coordinate, so get that one only then :)
