Question

Write the standard form of the equation of the line with slope-3 passing through the point (-1,-6)

1 Answer

  • y = mx + b
    slope(m) = -3
    (-1,-6)...x = -1 and y = -6
    now we sub and find b, the y int
    -6 = -3(-1) + b
    -6 = 3 + b
    -6 - 3 = b
    -9 = b

    y = -3x - 9...add 3x to both sides
    3x + y = -9 <== standard form
