Find the slope, if it exists, of the line containing the pair of points. (8,-4) and (8,-9)
The slope is __
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
Using the given points (8, -4) and (8, -9), we have:
slope = (-9 - (-4)) / (8 - 8)
= (-9 + 4) / 0
= -5 / 0
The denominator is 0, which means that the slope does not exist for this line.
