Question 184316
<font face="Times New Roman" size="+2">


Use the mid-point formula:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \ \ (x_m,y_m) = \left( \frac{x_1 + x_2}{2} \ , \ \frac{y_1 + y_2}{2}\right)]


So, demonstrate that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \ \ (7,9) = \left( \frac{-1 + 15}{2} \ ,\  \frac{-6 + 24}{2}\right)]
