Find the Cartesian equation of the line passing through A(1, 2, 3) and having direction ratios 2, 3, 7
उत्तर
The Cartesian equation of the line passing through A(x1, y1, z1) and having direction ratios a, b, c is
`(x - x_1)/a = (y - y_1)/b = (z - z_1)/c`
∴ The Cartesian equation of the line passing through A(1, 2, 3) and having direction ratios 2, 3, 7 is
`(x - 1)/2 = (y - 2)/3 = (z - 3)/7`
