## Homework Statement

z = 2x^2 + 5y^2 +2

C is cut by the plane x = 2

Find parametric eqns of the line tangent to C @ P(2, 1, 15)

## Homework Equations

z = 5y^2 + 10

dz/dx = 10y

dz/dx (1) = 10

## The Attempt at a Solution

z = 10y + 15

y = t + 1

if the slope is 10/1 then delta z = 10 and delta y = 1. Therefore those values are multiples in front of t for the z and y parametric eqns respectively. Is this correct?

Thanks in advance.
