Your number line has zero in the centre. On the right are the positive numbers 2 and 5, with 5 being the furthest to the right. The negatives are on the left, -10 being 10 units to the left followed by -8 and -4, -4 being the closest to zero on the left. Read the numbers from left to right (ignore zero because it’s not in the list). This gives you the right order.
