1.) Let P(-2,3,1), Q(2,8,0), and R(6,3,-1). Use a product of vectors to find the area of the triangle with vertices P, Q, and R. (8 pts) 2.) Find the equation of the line thru P(2,-3,-1) that is perpendicular to the plane 2x-5y+z=10 in a) scalar parametric form and b) symmetric form. (8 pts) 1.) Let P(-2,3,1), Q(2,8,0), and R(6,3,-1).
