Point A : (15, -2) Point B : (-5, 2)

The slope of line m is
.

Answer 1

To find the slope of line \( m \) that goes through points \( A(15, -2) \) and \( B(-5, 2) \), we can use the slope formula:

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

Let's assign the points:
- \( A = (x_1, y_1) = (15, -2) \)
- \( B = (x_2, y_2) = (-5, 2) \)

Now substitute the coordinates into the slope formula:

\[
m = \frac{2 - (-2)}{-5 - 15}
\]
\[
m = \frac{2 + 2}{-5 - 15}
\]
\[
m = \frac{4}{-20}
\]
\[
m = -\frac{1}{5}
\]

Therefore, the slope of line \( m \) is

\[
\boxed{-\frac{1}{5}}
\]
