What is the slope of a line that passes through (5, 2) and (8, 1)?

How to work out slope of a line:

Take the y coordinate of the first point, and subtract it from the y coordinate of the the second point, like so:

y₁ - y₂ = 2 - 1

         = 1

(note: y₁ is the y coordinate of the first point, and y₂ is the y coordinate of the second point)

Next, take the x coordinate of the first point and subtract it from the x coordinate of the second point, like so:

x₁ - x₂ = 5 - 8

         = -3

(note: x₁ is the x coordinate of the first point, and x₂ is the x coordinate of the second point)

----------------------------------------------

Now to get the slope, all we do is divide the value of (y₁ - y₂) by (x₁ - x₂):
