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!
