Final answer:
The slope of the line passing through the points (-5,6) and (-9,-6) is calculated using the slope formula and results in a positive slope of 3.
Step-by-step explanation:
The slope of a line can be calculated using the formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are coordinates of two distinct points on a line. Applying this formula to the points (-5,6) and (-9,-6), we get:
slope = (-6 - 6) / (-9 - (-5))
slope = (-12) / (-4)
slope = 3
The slope of the line in simplest form that passes through the given points is 3 which indicates a positive slope.
