To find the slope of the line passing through the points (2,-1) and (10,-10), we can use the formula for slope:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates of the two points, we can substitute the values into the formula:
slope = (-10 - (-1)) / (10 - 2)
Simplifying the numerator and denominator:
slope = (-10 + 1) / (10 - 2)
slope = -9 / 8
Therefore, the slope of the line is -9/8.
