Susan wants to find an estimate for the number of fish in a lake. On Monday she catches some fish and marks each with a non-harmful dye.
She then returns those fish to the lake.
On Tuesday Susan catches 24 fish and 16 of these have the dye on them.
Using her sampling information, Susan estimates the total number of fish in the lake to be 192.
How many fish must Susan have marked with the dye on Monday?

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

the answer is d

hope this
