find the slope of the line that passes through (10,-8) and (1,12)
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 (10, -8) and (1, 12):
slope = (12 - (-8))/(1 - 10)
= 20/(-9)
= -20/9
Therefore, the slope of the line that passes through (10, -8) and (1, 12) is -20/9.
