What is the equation of the line with slope 3 that passes through the point (1, 2)?
Correct Answer: y - 2 = 3(x - 1)
- Step 1: Identify the slope (m) and the point (x1, y1). Here, the slope is 3 and the point is (1, 2).
- Step 2: Write down the point-slope form of the equation of a line, which is y - y1 = m(x - x1).
- Step 3: Substitute the values into the equation. Replace y1 with 2, m with 3, x1 with 1.
- Step 4: The equation becomes y - 2 = 3(x - 1).
