1. The problem statement, all variables and given/known data Find the distance from the origin to the line x=1+t y=2-t z=-1+2t 2. Relevant equations Possibly d=|aXb| / |a| 3. The attempt at a solution I think I need to use the formula provided above, but I'm not sure how. A different distance formula was covered in class, but I think there are different formulas to use based on what you're trying to find the distance between. There is an example in the textbook like this that asks to use this formula, but it gives out three points and tells assigns vectors for a and b. I'm not sure how to approach this.
