Question

Write the equation of a line that has a slope of 2 and goes through (3,-4).

1 Answer

  • First, start with the basic line equation:
    y = mx + b
    Then, fill in what you know.
    -4 = 2(3) + b
    Solve for b
    -4 = 6 + b
    -6   -6
    -10 = b
    Now you have your equation:
    y = 2x - 10

    I hope this helps :)
