Q. Find the slope of the line that passes through (10,8)(10, 8) and (8,9)(8, 9).\newlineWrite your answer in its simplest form.
  1. Slope Formula: To find the slope of the line that passes through two points, we use the slope formula: slope mm = y2y1x2x1\frac{y_2 - y_1}{x_2 - x_1}, where (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) are the coordinates of the two points.\newlineLet's assign the points as follows: (x1,y1)=(10,8)(x_1, y_1) = (10, 8) and (x2,y2)=(8,9)(x_2, y_2) = (8, 9).\newlineNow we can plug these values into the slope formula.
  2. Assign Points: Calculate the difference in the y-coordinates y2y1y_2 - y_1: 98=19 - 8 = 1.
  3. Calculate y-coordinate difference: Calculate the difference in the x-coordinates (x2x1)(x_2 - x_1): 810=28 - 10 = -2.
  4. Calculate x-coordinate difference: Now, divide the difference in y-coordinates by the difference in x-coordinates to find the slope: slope mm = 12\frac{1}{-2} = 12-\frac{1}{2}.
  5. Find Slope: The slope of the line that passes through the points (10,8)(10, 8) and (8,9)(8, 9) is 12-\frac{1}{2}. This is a proper fraction and represents the rate at which the line rises or falls as it moves from left to right.
