Question

find the coordinates of a point P which divides the line segment joining P= - 7,2 and q=-1,-1 in the ratio 4:1​

Answer 1

Step-by-step explanation:

By taking equal co-ordinates:

$\frac{m1}{m2} = \frac{x - x1}{x2 - x} \: or \: \frac{y - y1}{y2 - y}$

(I).X1=-7, X2=-1

4/1=x-(-7)/-1-x

4(-1-x)=x+7

-4-4x=x+7

-4-7=x+4x

-11/5=x.

(ii). y1=2 y2=-1.

4/1=y-2/-1-y

4(-1-y)=y-2

-4-4y=y-2

-4+2=y+4y

-2/5=y
