a - b, a(2, 4) b(-3, 7). сумма координат а - b

To find the sum of the coordinates of a - b, we subtract the x-coordinates and the y-coordinates separately.

Given: a(2, 4) b(-3, 7)

Let's subtract the x-coordinates: 2 - (-3) = 2 + 3 = 5

Now, let's subtract the y-coordinates: 4 - 7 = -3

The sum of the coordinates a - b is (5, -3).
