Slope of the line through the points (2,1) and (4,2) is

slope =

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (4, 2)

m = =

We can use to find the slope, where and are both points.

Plug in the values.

Subtract.
