To find the slope of a line that passes through two points, you can use the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, the two points are (4, 10) and (1, 11), so substituting these values into the formula gives:
slope = (11 - 10) / (1 - 4) = 1 / -3 = -1/3
So, the slope of the line that passes through (4, 10) and (1, 11) is -1/3.
