Final answer:
The slope of the line that contains the points (-3,5) and (3,-9) is -7/3.
Step-by-step explanation:
To find the slope of the line that contains the points (-3,5) and (3,-9), we can use the formula for slope: m = (y2 - y1) / (x2 - x1). Plugging in the values from the points, we get m = (-9 - 5) / (3 - (-3)). Simplifying, we have m = -14 / 6, which can be further simplified to m = -7/3. Therefore, the slope of the line is -7/3.
