A. -6
B. 3
C. -3
D. -1

Answer 1

To find the slope of the line defined by the given points, we'll use the formula for the slope (m) between two points \((x_1, y_1)\) and \((x_2, y_2)\):

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

From the data, we can choose any two points. Let's use the points (1, -3) and (2, -6):

- Point 1: \((x_1, y_1) = (1, -3)\)
- Point 2: \((x_2, y_2) = (2, -6)\)

Now apply the slope formula:

\[
m = \frac{-6 - (-3)}{2 - 1}
\]

This simplifies to:

\[
m = \frac{-6 + 3}{1} = \frac{-3}{1} = -3
\]

Thus, the slope of the line is:

C. -3
