Find the coordinates of the point P

Solution

equation of horizontal line passing through (0,3) is y =3

equation of slant line passing throgh (0,-1),(3,0) is

y-(-1)=[^(0-(-1))/_(3-0)]*(x-0)

y+1=(1/3)x

y =(1/3)x -1

solving y =(1/3)x -1 , y=3

(1/3)x -1=3

(1/3)x= 4

x=4*3

x=12

coordinates of P are (12,3)
