Using the slope formula find the slope of the line through the given points (8,7) and (6,9)
The slope formula is given by:
m = (y₂ - y₁) / (x₂ - x₁)
Substituting the coordinates of the given points into the formula:
m = (9 - 7) / (6 - 8)
Simplifying:
m = (2) / (-2)
m = -1
Therefore, the slope of the line passing through the points (8,7) and (6,9) is -1.
