A line passes through the points (2, 5) and (4, k). If the slope of the line is 3, what is the value of k?

✓ Correct Answer: Option C

The slope of a line is calculated as (y₂ - y₁) / (x₂ - x₁). Given points (2, 5) and (4, k) with a slope of 3, we have 3 = (k - 5) / (4 - 2). Simplifying, 3 = (k - 5) / 2. Multiply by 2: 6 = k - 5. Therefore, k = 11.
