Answer:
Negative correlation
y= -5x +25
Explanation:
The scatter plot shows a negative correlation between time (years) and the number of Sumatran tigers, that is, the population is decreasing.
In order to find an equation for the trend line, apply two points from the plot to the general equation for straight lines:
[tex]y-y_{0}=m(x-x_{0})\\25-0=m(0-5)\\m=-5\\y-25 = -5(x - 0)\\y= -5x +25[/tex]
