The unit vector that is in the same direction as v is given by:
The vector is given by the <u>terminal point subtracted by the initial point,</u> hence:
v = (-17, 4) - (7, -9) = <-24, 13>
<h3>How to find the unit version of a vector?</h3>Each coordinate of the vector is <u>divided by it's norm</u>.
