  1. hi dude formula for slope when given in ax+by+c=0is -a/b

    so the answer is 4/5(C)


  2. C

  3. C  

  4. Write in slope intercept form

    -4x + 5y = 15

    Add 4x to both sides

    5y = 15 + 4x

    Manipulate so it will end up as y = mx+b

    5y = 4x + 15

    Divide through by 5

    y = 4/5x + 3

    m = slope

    m=4/5

    Answer = c
