Question

Assertion (A): The value of q=+2, if x = 3,y=1 is the solution of the line 2x+y-q²-3=0

Reason (R): The solution of the line will satisfy the equation of the line
a) If both the assertion and the reason are true and the reason is a correct explanation of the assertion.

b) If both the assertion and reason are true but the reason is not a correct explanation

of the assertion

c) Assertion is true but reason is false d) Assertion is false but reason is true​

Answer 1

answer a

Step-by-step explanation:

assertion and reason both true reason is the correct explanation

Answer 2

Given : Assertion (A): The value of q=±2, if x = 3,y=1 is the solution of the line 2x+y-q²-3=0

Reason (R): The solution of the line will satisfy the equation of the line

To Find : Correct option

Solution:

Assertion (A): The value of q=+2, if x = 3,y=1 is the solution of the line 2x+y-q²-3=0

2x+y-q²-3=0

x = 3,y=1 is the solution

=> 2(3) + 1 - q²  - 3 = 0

=> q²  = 4

=> q = ±2

Value of q can be  +2 or -2

CORRECT

Reason (R): The solution of the line will satisfy the equation of the line

CORRECT

both the assertion and the reason are true and the reason is a correct explanation of the assertion.
