geno... I think you had a mistake.

The formula for inverse proportion is x= k/y.

From the x and y values we were given, we can find out that 2=k/4.

We can figure out that k=8.

Now the equation: Since we know k, we can plug in k as x, and y as 1 from the given value.

x=8/1.

Therefore, x will be equal to 8.

This would be about 1.5212011806014482 which would round to 1.5212.

@Melody, I think the problem is just saying that every time Mia shoots a duck, the ducks next to it fall down. Then, how many ways can Mia shoot three ducks? This should be clear now.

Let's say that y=mx+b, m=slope, b=y-intercept

y=-6x+b
We can solve for b using given coordinates on the line (-3,5)
5=-6*(-3)+b
b=-13
 

Therefore, the equation would be y=-6x-13.

Hope this helped!

Mia can only shoot at  Ducks 2-9, since there is no duck to the left of Duck 1 or to the right of Duck 10.

Therefore, the equation will be (9-2+1) ! which is 40320 ways.

Hope this helped!
