What is the slope of line AB that contains points A(0, 1) and B(1, 5)?

To find the slope of the line AB, we can use the formula:

Slope (m) = (y₂ – y₁) / (x₂ – x₁)

In this case, we have the points A(0, 1) and B(1, 5). Here, (x₁, y₁) is (0, 1) and (x₂, y₂) is (1, 5).

Now plug in the coordinates:

• y₂ = 5
• y₁ = 1
• x₂ = 1
• x₁ = 0

So the slope becomes:

Slope (m) = (5 – 1) / (1 – 0) = 4 / 1 = 4

Therefore, the slope of line AB is 4.
