Question

2. If the co-ordinate of A is x and that of B is y, find d(A, B) .

(i) x = 1, y = 7 (ii) x = 6, y = - 2 (iii) x = - 3, y = 7

(iv) x = - 4, y = - 5 (v) x = - 3, y = - 6 (vi) x = 4, y = - 8​

Answer 1

⠀$\huge{\underline{\underline{\boxed{\sf{\red{Aɴsᴡᴇʀ\: ࿐}}}}}}$

i. Co-ordinate of point A is x = 1.

Co-ordinate of point B is y = 7

Since, 7 > 1

∴ d(A, B) = 7 – 1

∴ d(A, B) = 6

ii. Co-ordinate of point A is x = 6.

Co-ordinate of point B is y = -2.

Since, 6 > -2

∴ d(A, B) = 6 – ( -2) = 6 + 2

∴ d(A, B) = 8

iii. Co-ordinate of point A is x = -3.

Co-ordinate of point B is y = 7.

Since, 7 > -3

∴ d(A, B) = 7 – (-3) = 7 + 3

∴ d(A, B) = 10

iv. Co-ordinate of point A is x = -4.

Co-ordinate of point B is y = -5.

Since, -4 > -5

∴ d(A, B) = -4 – (-5) = -4 + 5

∴ d(A, B) = 1

v. Co-ordinate of point A is x =-3.

Co-ordinate of point B is y = -6.

Since, -3 > -6

∴ d(A, B) = -3 – (-6) = -3 + 6

∴ d(A, B) = 3

vi. Co-ordinate of point A is x = 4.

Co-ordinate of point B is y = -8.

Since, 4 > -8 l

∴ d(A, B) = 4 – (-8) = 4 + 8

∴ d(A, B) = 12
