Slope of (2,8) and (1,-3)

Question

Slope of (2,8) and (1,-3) 

Answer 1

m = (y₂ - y₁)/(x₂ - x₁) = (y₁ - y₂)/(x₁ - x₂)

 

x₁ = 2

y₁ = 8

 

x₂ = 1

y₂ = -3

 

Just plug in the numbers.

Answer 2

The slope of a line is rise/run.  In other words, it is the difference between the y coordinates divided by the difference in the x coordinates.
