Please see the explanation.

Explanation:

TM is the vector from T to M; it is customary to write a bar over the vector, #bar(TM)#, and enclose the ordered triple with < > symbols.

Subtract the x,y, or z coordinate of point T from the corresponding coordinate of point M:

#bar(TM) = < (-3 - -2), (5 - 4), (2 - 7)>#

This is the vector from T to M:

#bar(TM) = < -1, 1,-5>#
