write the equation of the line with slope 2 that passes through the point (-1,5)

  • Math -

    recall slope-point form:
    y - y1 = m(x - x1)
    where
    m = slope
    (x1, y1) = point on the line
    thus,
    y - 5 = 2(x - (-1))
    y = 2(x + 1) + 5
    y = 2x + 2 + 5
    y = 2x + 7

    hope this helps` :)
