    Hey, not sure how to translate this from my native language, I hope you understand what I mean.

    Write down for the line
    y = 2x + 3 perpendicular and parallel lines passing through the point
    (1; 1) equations.

    Write down for the line
    y = 2x + 3 perpendicular and parallel lines passing through the point
    (1; 1) equations.
    using the point-slope form, $y-y_1 = m(x-x_1)$

    parallel lines have the same slope ...

    $y-1 = 2(x-1)$

    perpendicular lines have slopes that are opposite reciprocals ...

    $y - 1 = -\dfrac{1}{2}(x-1)$

    ... and this post belongs in Pre-algebra and Algebra, not Linear and Abstract algebra
