I need the answer as soon as possible Transcribed Image Text: EXAMPLE 1
Use t = y to parametrize the part of the line of intersection of the
two planes y = 2x – 4 and z = 3x +1 from (2, 0, 7) to (3, 2, 10).
The plane x+ y = I intersects the paraboloid z = x² +
in a parabola. Parametrize the whole parabola using t = x as

parameter. Could t = y have been used as parameter? What about t = z?
Parametrize the curve of intersection of the plane x +2y+4z = 4
and the elliptic cylinder x²+ 4y² = 4.
EXAMPLE 4
2+4y? = 4
x+2y +4z = 4
