Answer:
x + y - 5 = 0
Step-by-step explanation:
(x-4)² + (y+3)² = 16
To remove the square on the left side, we square root both sides
√(x-4)² + √(y+3)² = √16
The square will cancel the square root on the left side, while the square root of 16 is 4
(X-4) + (y+3) = 4
open the brackets
x-4+y+3=4
x + y = 4 + 4 - 3
x + y = 5
x + y - 5 = 0
