Equation of lineEasyQuestion 300002
Question
The equation of a line with slope m passing through (x₁, y₁) is:
- Ay − y₁ = m(x − x₁)Correct
- By = mx
- Cy₁ = m(x − x₁)
- Dx − x₁ = m(y − y₁)
Correct answer
y − y₁ = m(x − x₁)
Explanation
Point-slope form: y − y₁ = m(x − x₁). This is the most versatile form for writing line equations given a point and slope.
