Answer:


(x,y) = (\¾, (5)/(2))

Explanation:

Given


Ratio = 1 :3


A = (-3, 2)


B = (12 , 4)

Required

Determine the coordinates at the given ratio

This is calculated using the following formula


(x,y) = (mx_2 + nx_1)/( m + n), (my_2 + ny_1)/(m + n)

Where:


m : n = 1 : 3

Substitute values for x1, x2, y1, y2, m and n


(x,y) = ((1 * 12 + 3 * -3)/(1 + 3),(1 * 4 + 3 * 2)/(1 + 3))


(x,y) = ((12-9)/(4),(4 + 6)/(4))


(x,y) = (\¾,(10)/(4))

The coordinates is at point:
(\¾, (5)/(2))
