Question

Find the slope of the line passing through the points (4, 4) and (4, - 4) .

Answer 1

• Slope = undefined

Explanation:

We know that:

• Slope Formula = y₂ - y₁/x₂ - x₁

Solution:

• y₂ - y₁/x₂ - x₁ = -4 - 4/4 - 4
• => -8/0 = undefined

Since the slope of the line is un-defined, the line is vertical. Please look at my graph to understand better.
