Final answer:

The expression that can be used to find the slope is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are any two points on the line.

Step-by-step explanation:

The expression that can be used to find the slope is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are any two points on the line.

  1. Choose two points on the line.
  2. Substitute the coordinates of the two points into the formula.
  3. Calculate the difference in the y-coordinates and the difference in the x-coordinates.
  4. Divide the difference in the y-coordinates by the difference in the x-coordinates to find the slope.

For example, if we have two points (3, 5) and (7, 9), the slope would be (9 - 5) / (7 - 3) = 4 / 4 = 1.
