Question

point k lies at (-3,4) Image

Answer 1

Answer:

$k(x,y) --> k'(x,y-7)$

Step-by-step explanation:

Given

$k = (-3,4)$

Translation: 7 units down

Required

Determine the rule to produce k'

When an (x,y) coordinate is translated down by h units, the resulting point is:

(x,y) --> (x, y - h)

In this case:

$h = 7$

So, we have:

$k(x,y) --> k'(x,y-7)$

Hence, option A answers the question.

Solving further to determine the coordinates of k'.

$k = (-3,4)$

$k' = (-3,4-7)$

$k' = (-3,-3)$
