A science class helped to estimate the population of various species in their local woods. Initially they tagged various numbers of 3 different species. The class then returned several weeks later to count each of the species that they had originally tagged. For each species, they kept track of the total
counted, and the number with tags. Here are their results:

Based on the data samples collected, which statement shows a reasonable estimate?
There are about 87 owls in the woods.
There are more owls than quails in the woods.
There are approximately twice as many owls as lynxes.
The species that was tagged the most has the highest population

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
