Question

A point is translated on the coordinate plane from (4,−1)%0D%0A(%0D%0A4%0D%0A,%0D%0A−%0D%0A1%0D%0A)%0D%0A to (4,2)%0D%0A(%0D%0A4%0D%0A,%0D%0A2%0D%0A)%0D%0A. Journey writes the function g(y)=y+k%0D%0A𝑔%0D%0A(%0D%0A𝑦%0D%0A)%0D%0A=%0D%0A𝑦%0D%0A+%0D%0A𝑘%0D%0A to describe the translation. What is the value of k?(1 point)%0D%0AResponses%0D%0A%0D%0A−5%0D%0A−%0D%0A5%0D%0Anegative 5%0D%0A%0D%0A3%0D%0A3%0D%0A%0D%0A0%0D%0A0%0D%0A%0D%0A−3

Answer 1

k = 3

Explanation: The y-coordinate goes from −1 to 2, an increase of 3, so g(y) = y + 3 (the translation is (0, 3)).
