Write the standard form of the equation of the line through the given point with the given slope. Through: (3,-1) and (8,-4)

  • algebra -

    Slope = (-4 - (-1))/(8-3) = -3/5

    using the point (3,-1)
    y+1 = (-3/5)(x-3)
    5y + 5 = -3x + 9
    3x + 5y = 4

    Test my subbing in the point not used, it works.
