What is the slope of the line that passes through (2, 12) and (4, 20)?

Solution:

The formula used to determine the slope of points (x₁, y₁) and (x₂, y₂) is

m = (y₂ - y₁)/ (x₂ - x₁)

The points given are (2, 12) and (4, 20)

Substituting the values in the formula

m = (20 - 12)/ (4 - 2)

By further calculation

m = 8/2

So we get

m = 4

Therefore, the slope of the line is 4.

What is the slope of the line that passes through (2, 12) and (4, 20)?

Summary:

The slope of the line that passes through (2, 12) and (4, 20) is 4.
