Answer 1

(-9,2) + 6,4 + (-3,6) + 1,6

-9,2 + 6,4 - 3,6 + 1,6

-9,2 + 2,8 + 1,6

-9,2 + 4,4 = - 4,8

Answer 2

It seems like you want to add the given pairs of numbers. Each pair consists of two values: a number in front of the comma (",") represents the x-coordinate, and the number after the comma represents the y-coordinate. I'll perform the addition for each coordinate separately:

Let's add the x-coordinates first: -9 + 6 + (-3) + 1 = -5

Now, let's add the y-coordinates: 2 + 4 + 6 + 6 = 18

So, the sum of the given pairs of numbers is (-5, 18).
