+874 Slope: $\frac{36-30}{23-0} = \frac{6}{23}$
$y = \frac{6}{23} x + b$
$30 = b$
$y = \frac{6}{23} x + 30$
$y \in \mathbb{R}$
For the last box, I don't know the options, so how about you show us the options for the last one.
+36916 The domain is the scope of the 'x' values [0,23] which represents years.
