What is the slope of the line?
Write your answer as an integer or simplified fraction.

Answer 1

To find the slope of the line formed by the given points, we can use the slope formula:

\[
\text{slope} (m) = \frac{y_2 - y_1}{x_2 - x_1}
\]

Let's take two points from the data: \((x_1, y_1) = (9, 3)\) and \((x_2, y_2) = (12, 30)\).

Using these coordinates, we can plug them into the formula:

\[
m = \frac{30 - 3}{12 - 9} = \frac{27}{3} = 9
\]

Thus, the slope of the line is \( \boxed{9} \).
