Question

a point is translated on the coordinate plane from (5, -3) to (5,7). journey needs to write the function g(y)=y + k to describe the translation. what is the value of k? (1 point)
10
0
4
-10

Explanation:

Step1: Identify initial and final y - values

Initial y - value is $y_1=-3$, final y - value is $y_2 = 7$.

Step2: Use translation formula

The translation formula is $y_2=y_1 + k$. Substitute $y_1=-3$ and $y_2 = 7$ into it: $7=-3 + k$.

Step3: Solve for k

Add 3 to both sides of the equation: $k=7+3$. So, $k = 10$.

Answer:

10
