Question
Find the slope of the line that passes through (1, 2) and (9, 9).Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Solution
The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Here, (x1, y1) = (1, 2) and (x2, y2) = (9, 9)
So, the slope = (9 - 2) / (9 - 1) = 7 / 8
Therefore, the slope of the line that passes through the points (1, 2) and (9, 9) is 7/8.
