Find the equation of the plane that contains the point A(2, 1, – 1) and is perpendicular to the line of intersection of the planes 2x + y – z = 3 and x + 2y + z = 2. Also find the angle between the plane thus obtained and the y-axis.
Equation of plane that contains the point A(2,1,–1)
Accordinf to the condition;
Equation(i) + Equation (ii)
3a + 3b = 0
a = -b
c = -b =a
