The slope of the line that contains the points (7, -1) and (6,-4) can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
Substituting the coordinates (7, -1) and (6,-4) into the formula, we get:
slope = (-4 - (-1)) / (6 - 7)
Simplifying the expression gives:
slope = (-4 + 1) / (-1)
slope = -3
So, the slope of the line that contains the points (7, -1) and (6,-4) is -3.
