1. The problem statement, all variables and given/known data Find the coordinates of three points on each of the following lines. a. (x+2)/3=(y-1)/2=(z+5)/(-3) x = -1 + 5t b.y = 7 + t z = 3 - 2t 2. Relevant equations (x+2)/3=(y-1)/2=(z+5)/(-3) x = -1 + 5t y = 7 + t z = 3 - 2t 3. The attempt at a solution I'm guessing that they mean the (x,y,z) coordinates by saying "Find the three coordinates." I attempted a), and found the three coordinates to be (-3.5,0,-3.5), but am unsure if this is correct. I also am lost on how to attempt the second one, b). any help is appreciated!
