What is the slope of the line passing through the points (1, 2) and (5, 4)?

, or the first option

Step-by-step explanation:

The formula to find the slope of a line is . It doesn't matter which set of coordinates is (x₁,y₁), as long as you make sure you put them in the right places.

(x₁,y₁) = (1,2)

(x₂,y₂) = (5,4)

  Plug in your numbers

  Simplify

slope =

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (5, 4)

m = = =
