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 = $\frac{12}{10}$ = 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.
