a) Determine if the line [x, y, z] [4, 1,-2] t[3, 1, -5] has x-, y, and/or zintercepts. b) Under what conditions will a line parallel to [x, y, z] [4, 1, -2] t[3, 1, -5] have only i) an xintercept? ii) a yintercept? iii) a zintercept? 0) Under what conditions (if any) will a line parallel to the one given have an x-, a y, and a z-intercept
