In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A):The slope of the line whose equation is 5x + 6y = 7 is − 5/6 and the y-intercept is 7/6
Reason(R): The equation of straight line which makes an angle θ with x-axis and intercept c on the y-axis is y = mx - c, where m = tan θ
Assertion(A):ABC is a triangle, where A ≡(2,3,5), B ≡ (-1,3,2) and c ≡ (λ,5,μ). If the median through A is equally inclined towards the axes, then the values of λ and μ are respectively 7 and 10.
Reason(R): If median through A is equally inclined to the axis, then its direction ratios will be equal (say k), where k is a constant.
If A is a non-zero column matrix of order m x 1 and B is a non-zero row matrix of order 1 x n, then rank of AB is equal to
