Question
Please show work so that I can compare it to the work that I have attempted. Thanks.
a) The line through (4,1,2) and (1,1,5).
b) The line FROM (4,-1,2) TO (1,1,5).
c) The line through (1,0,-1) and parallel to the line x = 3t, y = 6, z = t - 9.
d/7) The line through (1,0,1) and (4,-2,2) intersect the plane x + y + z = 6.
my attempts: for
a) I got x = 4 -3t, y = -1, z = 2+3t.
b) I am not too sure what the difference is between FROM vs through.
c) so far I have x - 1 = 3t, y - 0 =0, z+1 = t
d/7). not sure how to do this one but this is how i started.
<4-1, -2-0="" 2-1=""> goes to <3,-2,1>. so t<3,-2,1>.
