HW 10 Algebra II Honors – Mr. Petach Please write your answers on a separate sheet! 1. Find a parametric equation of the line containing the points (a) (4 , 5 , 3) and ( - 1 , 7 , 2) (b) (0 , 4 , - 2) and ( - 3 , 1 , 3) (c) (0 , 0 , 0) and (1 , 1 , 1) (d) (3 , 4 , 5) and (3 , 6 , 8) 2. Find the point where the line you found in 1a) pierces (a) the xy plane. (b) the xz plane. (c) the yz plane. 3. For each of the following pairs of points, find the direction cosines ( c 1 , c 2 , and c 3 ) of a line containing the two points. Then, find a normalized parametric equation of the line. (a) 4 , 5 , 3) and ( - 1 , 7 , 2) (b) (0 , 0 , 0) and (1 , 1 , 1) (c) (4 , - 2 , 0) and (2 , - 2 , 0) 4. Do the lines L 1 and L 2 intersect? If so, find the point of intersection. If not, are they parallel? L 1 : x = 4 + 2 t y = 4 - 3 t z = 5
