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

To find the sum of the coordinates of a - b, we need to subtract the corresponding coordinates of b from a.

Given that a has coordinates (2, 4) and b has coordinates (-3, 7), we can subtract the x-coordinates and the y-coordinates separately.

The x-coordinate of a - b = 2 - (-3) = 2 + 3 = 5 The y-coordinate of a - b = 4 - 7 = -3

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