Answer
$y= 16.49 - 0.00282x$
$15.09$
Work Step by Step
Let X be the amount of lemon imports. Y is the Crash Fatality Rate.
$\sum X=1863$
$\sum Y=77.2$
$\sum X\times Y=28571.7$
$\sum X^{2}=762589$
$a=16.49 \rightarrow b=-0.0028$
We can use the equation formula: $y= a + bx = 16.49 - 0.00282x$
Substitute x with $500$: $y=16.49-0.0028\times500=15.09$
