I have the data and need to make a prediction based on it (probability)

Hello Everyone,
I really can't understand stats and it's driving me crazy.

I have data for births linked with different years, the graphic looks like this

But I need to make a prediction on the births in year 2010. How do I go about that?!

It looks like you are provided with the linear regression:

$$y=-0.1103x+234.98$$

Can you see what you need to use for $x$ to get a prediction for the year 2010?

I'm confused... Isn't x supposed to represent the years?

Yes, it appears to me that the independent variable $x$ is the year, and this input into the given line will give a prediction for the output, the dependent variable which is the birth rate, for that year.

So, use $x=2010$ in the given line, and what do you find?

Oh, so basically it's going to be 13.277?

Thank you!

Yes, that's the same value I get. (Yes)
