Answer 1

Answer:

Find the coordinates of the point which devices the join of (-1,3) and (4,-3) in the ratio of 3:1 ?

Answer 2

Answer:

Given: A:(x

1

,y

1

)=(−1,7)

B:(x

2

,y

2

)=(4,−3)

To find: P(x,y)suchthatAP:PB=2:3

Solution: From section formula, coordinates of point P that divides the line segment joining the points (x

,y

2

) in the ratio m:n are (

m+n

)

Hence, coordinates of point P are: (x,y)=(
