Linear Function: Plotting Points (36,-60) and (6,30) on a Graph

To solve this problem, we will compute the slope of the line that passes through the points $A(6, 30)$ and $B(36, -60)$.

Step 1: Apply the slope formula
The slope $m$ between two points $(x_1, y_1)$ and $(x_2, y_2)$ is computed as follows:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Substituting the values for points $A(6, 30)$ and $B(36, -60)$:
$m = \frac{-60 - 30}{36 - 6} = \frac{-90}{30} = -3$

Step 2: Analyze the slope
Since the slope $m = -3$ is negative, it indicates that the linear function is decreasing.

Therefore, the solution to the problem is a decreasing function.
