Answer 2

To find the values of the expressions on the coordinate plane, let's evaluate each of them step by step:

1. -2 + 4: -2 + 4 = 2

2. 4 + (-5): 4 + (-5) = 4 - 5 = -1

3. -2 + (-4): -2 + (-4) = -6

4. -1 целая 1/3 + 1/3: To add mixed numbers, we first need to convert them into improper fractions. -1 целая 1/3 = -(1 + 1/3) = -4/3 Now, add the fractions: -4/3 + 1/3 = (-4 + 1) / 3 = -3 / 3 = -1

So, the values on the coordinate plane are as follows:

1. -2 + 4 = 2
2. 4 + (-5) = -1
3. -2 + (-4) = -6
4. -1 целая 1/3 + 1/3 = -1
