Question

find the coordinate of the point which divides the join of (-1,7),(4,-3) in the ratio 2:3​

Answer 1

Answer:

We know that, the coordinates of the point dividing the line segment joining the points x

1

,y

Coordinates of point of intersection of line segment is

(

2+3

(2)(4)+(3)(−1)

,

2+3

(2)(−3)+(3)(7)

)

=(5/5,15/5)

=(1,3)
