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 …
Solution : \(m_1\) = -\(1\over 4\) \(m_2\) = -\(4\over k\) Two lines are perpendicular if \(m_1 m_2\) = -1 \(\implies\) (-\(1\over 4\))\(\times\)(-\(4\over k\)) = -1 \(\implies\) k = -1 Similar Questions If the straight line 3x + 4y + 5 – k(x + y + 3) = 0 is parallel to y-axis, then the value …
If x + 4y – 5 = 0 and 4x + ky + 7 = 0 are two perpendicular lines then k is Read More »
Solution : Let the equation of line be \(x\over a\) + \(y\over b\) = 1 …..(i) This line passes through (3,4), therefore \(3\over a\) + \(4\over b\) = 1 …….(ii) It is given that a + b = 14 \(\implies\) b = 14 – a in (ii), we get \(3\over a\) + \(4\over 14 – …
Solution : Since, Slope of line passing through two points is m = \(y_2 – y_1\over x_2 – x_1\). so, slope of chord passing through two points is \(4-(-3)\over 3-2\) = 7 Now, Tangent line is parallel to chord. Therefore slope of tangent line is equal to slope of chord, Hence slope of tangent line …
