Answer:

P(\frac{10}{3}, \frac{-2}{3})

Step-by-step explanation:

The question is incomplete; However

A = (-2, -4)

B = (6, 1)

Required

Determine coordinates of P

When line segment is divided in ratios, the following formula calculates the coordinates;

P(x,y) = \{\frac{mx_2 + nx_1}{m+n}, \frac{my_2 + ny_1}{m+n}\}

In this case;

m:n = 2:1

(x_1,y_1) = (-2, -4)

(x_2,y_2) = (6, 1)

So, the coordinates of P is calculated as thus

P(x,y) = \{\frac{2 * 6 + 1 * (-2)}{2+1}, \frac{2 * 1 + 1 * (-4)}{2+1}\}

P(x,y) = \{\frac{12 -2}{3}, \frac{2 -4}{3}\}

P(x,y) = \{\frac{10}{3}, \frac{-2}{3}\}

Hence, the coordinates of P is

P(\frac{10}{3}, \frac{-2}{3})
