Question

If (m+3,2) = (5,n-1) ,then the co- ordinates of point (m , n) are ?
(a) (-1,-3)
(b) (2,-3)
(c) (2,3)
(d) (1,3)

​

Answer 1

Answer:

when two points are equal,

it means that abscissa and ordinate of both points are equal.

=> m + 3 = 5

So, m = 5-3

=> m = 2

Similarly, 2 = n-1

=> 2+1 = n

=> n = 3

So, (m,n) = (2,3)

So, option (c) - (2,3) is correct

Answer 2

Answer:

option c : (2,3)

Step-by-step explanation:

as given

(m+3,2)=(5,n-1)

you get,

$m + 3 = 5 \\ = = > m = 5 - 3 \\ = = > m = 2$

now similarly,

$2 = n - 1 \\ = = > 2 + 1 = n \\ = = > n = 3$

hence coordinate point (m,n)=(2,3) [option c]
