Can someone check my answers? i'm not sure i have them all
what is the y-intercept of the plane whose equation is 4x + 5y z = 20?
(0, 4, 0) < my answer
(0, 5, 0)
(5, 0, 0)
(0, 0, 4)
question 2. which equation has intercepts at x(1, 0, 0), y(0, 1, 0), and z(0, 0, 2)?
x y + 2z = 4
3x 2y + 6z = 12
2x 2y + z = 2
4x 4y + z = 4
question 3. which equation is equivalent to x + 3y z = 3?
3x + 6y 3z = 6
4x + 12y 4z = 12
2x + 4y 2z = 8
2x + 3y 4z = 12
question 4.4. which of the following points lies in the plane 3x 2y + 4z = 12?
(2, 2, 3)
(5, 15, 2)
(4, 16, 2) < my answer
(4, 3,2)
