To find the point P, we have to use the following formulas


\begin{gathered} x=(a)/(a+b)(x_2-x_1)+x_1 \\ y=(a)/(a+b)(y_2-y_1)+y_1 \end{gathered}

Where a = 1, b = 7, x1 = -4, x2 = 12, y1 = 7, and y2 = -1. Let's use these values to find each coordinate.


\begin{gathered} x=(1)/(1+7)(12-(-4))+(-4)=(1)/(8)(16)-4=2-4=-2 \\ y=(1)/(1+7)(-1-7)+7=(1)/(8)(-8)+7=-1+7=6 \end{gathered}

Hence, the coordinates of point P are (-2, 6).
