    • @stanthonysfire6387
      @stanthonysfire6387 8 ปีที่แล้ว +3

      You multiply them by 3, as that is the denominator of the fraction 2/3. This cancels out the 3, making it 2, and 3y, and 12, respectively.

    @Martiaali that's why there's crime scene. beat cops and detectives don't do that shit, CSU does. unless you're a crime scene investigator (a scientist with a fancy title) you'll never ever need to know the slope of a line. i'm a criminal justice major, nobody is ever going to ask me to find the slope of a line that passes through (3, -1) and (-3, 5)

    -1 (-2x+3y=12) -1
