If the straight line 3x + 4y + 5 – k(x + y + 3) = 0 is parallel to y-axis, then the value of k is
Solution : A straight line is parallel to y-axis, if its y-coefficient is zero i.e. 4 – k = 0 i.e. k = 4 Similar Questions The slope of tangent parallel to the chord joining the points (2, -3) and (3, 4) is If the line 2x + y = k passes through the point […]
