(3.) The plane 2x + 3y – 4z = 5 intersects the x-axis at (a,0,0), the y-axis at (0,b,0), and the z-axis at (0,0,c). The value of a + b + c is?

  • Math Analysis -

    Where it intersects the x-axis, y=0 and z=0. What does that give you for the value of x.
    Use the equation of the plane,
    P: 2x + 3y – 4z = 5 to get the answer.

    Similar for the other 2 cases.
