Find a parametric equation for the line through the point (10,-6,4) and perpendicular to the plane 7x + 8y + 4z = 15 which is written using the coordinates of the given point and the coefficients of x, y, and z in the given equation of the plane.
Let z = 4 + 4t.
x=, y=, z=
(Type expressions using t as the variable.)
