The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the following formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the points (-11, 12) and (5, 4), we get:
m = (4 - 12) / (5 - (-11)) = -8 / 16 = -1/2
So the slope of the line passing through (-11, 12) and (5, 4) is -1/2.
