The point at which one coordinate is given lies on the coordinate line. In this case, the distance between the points is equal to the modulus of the difference between the two coordinates. Moreover, the distance from point A to point B is equal to the distance from B to A, that is, AB = BA. Let’s use this technique when solving the problem.
If M (- 4) and T (3), then
MT = TM = | -4 – 3 | = | – 7 | = 7.
Answer MT = TM = 7 units. neg.
