Find an equation of the line having slope and containing the given point.
M=4/5, (3, -7)
The equation of the line is Y=

I have tried to work this problem and could not get the answer. Please help me.

  • algebra -

    y = (4/5) x + b
    -7 = (4/5)(3) + b
    b = -7 -(12/5)
    b = -35/5 - 12/5
    b = - 47/5
    so
    y = (4/5) x - 47/5
    or
    5 y = 4 x - 47

  • algebra -

    m=-4/5, T(1/3)=7/4
