Dobrý deň, áno správna odpoveď je B.

Na číselnej osi vidíme, že medzi číslom 0 a 1 je päť dielikov. Z toho vypočítame, že hodnota jedného dielika je: (1-0)/5 = 0,2.
Postupným "skákaním" po dielikoch určíme hodnoty jednotlivých bodov (zľava): -1,2 , -0,2 , 0,8 a 1,3

Najväčší problém mohlo robiť určenie hodnoty bodu, ktorý je úplne napravo. Ten sa nachádza v strede medzi 1,2 a 1,4. Presne medzi týmito bodmi leží 1,3. To by sme vedeli vypočítať aj ako aritmetický priemer 1,2 a 1,4 : (1,2+1,4)/2 = 1,3. Počítanie cez aritmetický priemer mi príde v tomto prípade trošku komplikované.

Prajem pekný večer
