Let the equation of the plane, that passes through the point (1, 4, -3) and contains the line of intersection of the planes 3x−2y+4z−7 = 03x - 2y + 4z - 7\, = \,0 and x+5y−2z+9 = 0x + 5y - 2z + 9\, = \,0 be αx+βy+γz+3 = 0,\alpha x + \beta y + \gamma z + 3\, = \,0, then α+β+γ \alpha + \beta + \gamma \, is equal to
View answer and explanation
Correct option: A
-23
Option A (-23) is correct because it represents the sum of the coefficients α\alpha, β\beta, and γ\gamma in the equation of the plane that passes through the given point and contains the line of intersection of the two planes.
