Answer 1

To describe the translation of the point \((5, -3)\) to \((5, 7)\) using the function \(g(y) = y + k\), we need to determine the value of \(k\) that will take \(-3\) to \(7\).

Starting with the function: \[ g(y) = y + k \] we plug in the initial \(y\) value of \(-3\): \[ g(-3) = -3 + k \] We want \(g(-3)\) to equal \(7\): \[ -3 + k = 7 \] Now, we solve for \(k\): \[ k = 7 + 3 \] \[ k = 10 \]

Therefore, the value of \(k\) is \(10\).

So, the answer is \(10\).
