Match the equations A, B, C and D with the lines L₁, L₂, L₃ and L₄, whose graphs are roughly drawn in the given diagram.

A ≡ y = 2x;

B ≡ y - 2x + 2 = 0;

C ≡ 3x + 2y = 6;

D ≡ y = 2

The line 5x - ky + 3 = 0 passes through the point (x = y = 3). The value of k is :

1. -3

2. -6

3. 6

4. 3

Assertion (A) : 2x + y = 8 and 6x + 3y = 20 are two straight lines. To find whether the lines are parallel to each other or not, we need to find the slope of each line.

Reason (R) : If slopes of both the lines are same, they are parallel to each other.

1. A is true, R is false

2. A is false, R is true

3. Both A and R are true and R is the correct reason for A

4. Both A and R are true and R is the incorrect reason for A
