Step-by-step explanation:
The equation of the given line:

This equation is in the form
. Therefore, 1/3 is the slope.
To find a perpendicular line, take the opposite reciprocal of the slope (-1/old slope). Therefore, the slope of the perpendicular line is -3.
The equation of the perpendicular line: 
Answer: I am not sure exctly what the question is here but if you are wondering how many butterflies tatal for all species here it is:
North American Butterfrlies: 30
South American Butterflies: 18
Europe Butterflies: 12
Step-by-step explanation: To get the total number of butterflies per species you need to mulitply to find the correct ratio given the total number of North American Butterflies is 30
North American Butterflies to South American Butterflies is 5 to 3 so 30/5=6, you then multiply 3*6 to get 18 South American Butterflies.
Then since we now know there are 18 South American Butterflies and the ratio of those to Europe Butterflies are 3 to 2 we take 18/3=6, then multiply 2*6 to get 12 Europe Butterflies.
