Question

Write an equation for the translation of y = |x|. 13 units down

A. y = |–13x|

B. y – 13 = |x|

C. y = |x| + 13

D. y = |x| – 13

Answer 1

the idea for transitions for an equation like this is

`y = m|x - h| + k`
where m = slope
h = how much left or right (note the negative)
k = how much up or down

moving 13 down would mean
k = -13

so

`y = |x| - 13`
D. would be your answer
