Section 10.5: Problem 4 (1 point) Find the vector and parametric equations for the line through the point P = (4, 4, 3) and parallel to the vector (4, 4, 5). Vector Form: r(t) = D Parametric form (parameter t, and passing through P when t = 0): m = m(t) = y = y(t) = z = z(t) = Section 10.5: Problem 5 (1 point) Consider the line which passes through the point P(1, 4, 3), and which is parallel to the line a: = 1 + 7t, 3; = 2 + 415, z = 3 + t Find the point of intersection of this new line with each of the coordinate planes: my-plane: , , mzplane: , , yz-plane
