Your answer will be D

Answer:

b. - 0.6

Step-by-step explanation:

Since, the total coordinates from -2 to 10 = 10 - (-2) = 10 + 2 = 12,

Also, if it is divided into 10 congruent segments,

Then, the length of each segment = [tex]\frac{12}{10}[/tex] = 1.2,

That is, the difference between the marked point is 1.2,

So, the marked points from -2 to 10 are,

-2,   -0.8,   0.4,    1.6,   2.8,   4.0,   5.2,   6.4,    7.6,    8.8,    10,

Hence, except -0.6 all points are the marked points,

Option b is correct.
