Holli's house is located at (−1, 4). she can walk in a straight line to get to jedd's house. a fast food restaurant is located at (−3, 2) and partitions the way from holli's house to jedd's house by a ratio of 1: 2. find the coordinate of jedd's house.

The coordinate of Jedd's house is:

                          (-7,-2)

We know that if a Point P(a,b) partitions the line joining the point (x,y) and (x',y') in the ratio m:n

Then the coordinates of the point P is given by:

Here m:n=1:2

and (a,b)=(-3,2) i.e. location of the food restaurant.

and

(x,y)=(-1,4) i.e. location of Holli's house.

and (x',y') is the location of Jedd's house.

Hence, we have:
