QUESTION 26
Write parametric equations for the tangent line to the curve of intersection of the surfaces $z = 2x^2 + 5y^2$ and
z = x + y + 5 at the point (1, 1, 7).
x = -3t + 1, y = 3t + 1, z = -6t + 7
x = -9t + 1, y = 5t + 1, z = -6t + 7
x = -3t + 1, y = 5t + 1, z = -6t + 7
x = -9t + 1, y = 3t + 1, z = -6t + 7
