Final Answer:
The coordinates of point L, the midpoint of AC where \(A = -10\) and \(C = 10\), are \((0, 0)\).
Step-by-step explanation:
To find the coordinates of the midpoint L between two given points A and C, we use the midpoint formula:
![\[ L_x = \frac{{A_x + C_x}}{2} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/5k6to5qjrc3u8yq0exaihk3g2y6rhc1gjj.png)
![\[ L_y = \frac{{A_y + C_y}}{2} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/zbnvw2te39nk73jjczwbyl4h15u0jlry3n.png)
Given that \(A = (-10, A_y)\) and \(C = (10, C_y)\), substitute these values into the formula:
![\[ L_x = \frac{{-10 + 10}}{2} = 0 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/9lp6cg8k3hwf5saf0y2wswm8fvedap8q72.png)
![\[ L_y = \frac{{A_y + C_y}}{2} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/zbnvw2te39nk73jjczwbyl4h15u0jlry3n.png)
Since the y-coordinate of A and C is not provided, we express the result in terms of \(A_y\) and \(C_y\). The final coordinates of point L are \((0, \frac{{A_y + C_y}}{2})\).
If the y-coordinates of A and C are known, the specific numerical values for \(A_y\) and \(C_y\) can be substituted to obtain the exact coordinates of point L. If the y-coordinates are not given, the expression
represents the coordinates of L in terms of the unknown y-coordinates.
