Question

@Hero Another one, but I'm positive on my answer in this one.

Answer 1

Ms. Castellano showed her class two different functions, Function A and Function B. Function A is shown in the graph below.

Function B
y = –1/3 x + 5
Which of the following statements is true?
A. Both functions are linear, but only Function B has a negative rate of change.
B. Both functions are linear and have negative rates of change. <------
C. Only Function A is linear, but both functions have negative rates of change.
D. Only Function A is linear, and only Function B has a negative rate of change.

Answer 3

Ok, now tell me how you arrived at B

Answer 4

I just want to know if it's right or not...

Answer 5

That's good and all but that's not really what we're here for, we're help to help you work through your answers cause we can't be there for your test

Answer 6

...fine...
give me a moment...
The only reason is because I have to go to bed in like 5 minutes...so yeah..

Answer 7

Slope is the rate of change.

Answer 8

I'm not tire, it's 1 am here and my mom said if I don't get to bed then Im grounded. The joys of being 14. -_-

Answer 9

I did this on another website to find out what Function B was in a graph..

They're both linear and negative...

Answer 10

So I'm wrong. :(

Answer 11

@CrazyCountryGirl
A positive rate of change means a positive slope. That means as x becomes larger, y also becomes larger.
A negative rate of change means a negative slope. That means as x becomes larger, y becomes smaller.
