Find the equation of the line


With a slope of (-1/3) that goes through the point (2, -4)

With a slope of 3 that goes through the point (-5, -1)

    I'll do the second one for you.
    y=mx+b
    -1=3(-5)+b
    -1=-15+b
    14=b
    y=3x+14
    Basically, I'm just substituting in the formula y=mx=b.
    I hope I explained this well enough for you. I'm also in eighth grade and I was confused about this a few weeks ago.
