Question

Three friends start their journey from same point say along A and moves in different path say AB,AD,AC

Answer 1

Answer:

A = (-2,-2)

B=(2,-4)

Slope of the line = (-4-(-2))/(2-(-2))

= = 2/4

= -1/2

line

y = -x/2 + c

-2=1+c

=> c= -3

=> y = -x/2 -3

=> 2y = -x - 6

=> x = -(2y + 6)

AB=√(2-(-2))² + (-4-(-2))²

=> AB = √20

AP = √(x -(-2))² + (y - (-2))²

√(x + 2)² + (y + 2)² = √20

=> (x + 2)² + (y + 2)² = 20

x = -(2y + 6)

=> (-2y + 4)² + (y + 2)² = 20

=> 4(y + 2)² + (y + 2)² = 20

=> 5(y + 2)² = 20

=> (y + 2)² = 4

=> y + 2 = ± 2

=> y =0,- 4

x = -6, 2

(2,-4) is B

(-6, 0) is P

the coordinates of point is P (-6,0)
