Question

if the co-ordinates of o point
M are (-2,9) which con also be
expressed as (1+x, y^2) and y>o
then bind in which quadrant
p (y, x), Q(2,x) ,R( x^2,y-1),
s(2x - 3y)​

Answer 1

Answer:

Step-by-step explanation:

Suppose point C(x,y) divides the line segment joining points A(0,0) and B(9,12) in ratio 1:2

m

​  

=1,m

​  

=2

Then we can calculate the coordinates of C using section formula

(x,y)=[
