Answer:
-30
Explanation:
To find the slope of a line passing through two points (x1, y1) and (x2, y2), you can use the following formula:
{Slope} (m) = {y2 - y1}/{x2 - x1}
In your case, the two points are (12, -18) and (11, 12). So, you can calculate the slope as follows:
m = {12 - (-18)}/{11 - 12} = {12 + 18}/{-1} = {30}/{-1} = -30
The slope of the line passing through these two points is -30.
