Question

Describe how the graphs of y = |x| and y = |x| – 15 are related.

1. The graphs have the same shape. The y-intercept of y = |x| is 0, and the x-intercept of the second graph is –15.
2. The graphs have the same y-intercept. The second graph is steeper than y = |x|.
3. The two graphs are the same.
4. The graphs have the same shape. The y-intercept of y = |x| is 0, and the y-intercept of the second graph is –15.

Answer 1

Just plug in a 0 to each one...
y= 0
y = -15

Therefore the answer is 4.

Answer 2

Okay so now I have to graph y = |x| – 2. How would I do that?

Answer 3

plug in some points

Answer 4

when x is 0 what is y?

Answer 5

-2?

Answer 6

yep
