CHECK POINT 5 Consider the following procedure: Select a number. Multiply the number by 4. Add 6 to the product. Divide this sum by 2. Subtract 3 from the quotient. a. Repeat this procedure for at least four different numbers. Write a conjecture that relates the result of this process to the original number selected. b. Use the variable n to represent the original number and use deductive reasoning to prove the conjecture in part (a).

(2) (8 points) Determine normal vectors for the planes given by the equations x-y+2z = 3
and 2x + z = 3. Then determine a parametrization of the intersection line of the two
planes.

(a) (4 points) Find all vectors u in the yz-plane that have magnitude [u
also are at a 45° angle with the vector j = (0, 1,0).
