The vertices A and C of rhombus ABCD are A = (3, -1) and C = (-4, -8). The slope of diagonal BD is :

1. 7

2. -7

3. 1

4. -1

The line 5x + 3y = 15 meets y-axis at point P. The co-ordinates of point P are :

1. (0, 5)

2. (0, 3)

3. (5, 0)

4. (3, 0)

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 true, R is true

3. A is false, R is false

4. A is false, R is true
