Find the slope of the line that passes through (9, 10) and (2, 12).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
Using the coordinates (9, 10) and (2, 12), we can substitute the values into the formula:
m = (12 - 10) / (2 - 9)
m = 2 / (-7)
Simplifying the fraction, we have:
m = -2/7
So, the slope of the line passing through (9, 10) and (2, 12) is -2/7.
