What are you asking? Slope? If so. You would do change in y over change in x. So subtract 2 and -4 to get positive 6, then subtract 6 and -3 to get positive 9. Your slope is either 1/3 if it’s increasing, or negative 1/3 if it’s decreasing.
Answer:

It's B, I got it right. You would do chest thrusts if their torso is to big to reach around or if they're pregnant.
<u>Answer:</u>
<em>Biomagnifications largely affects the organisms at the highest trophic level.
</em>
<u>Explanation:</u>
The increase in concentration of toxic chemicals while moving up in a food chain is called biomagnification. What starts out as a small concentration at the lowest trophic level turns out to become a <em>higher concentration at higher trophic levels. </em>
Thus it is the organisms at the highest trophic level that are the most affected. This accumulation occurs because the organisms have not evolved enough to posess mechanisms that <em>facilitate detoxification of various substances. </em>
Such substances are called novel substances and DDT is an example. Removal of substances like metals is also difficult. Thus a harmful chemical component travels up various trophic levels increasing in <em>concentration at each trophic level.
