1. get the equation into y=mx+b form.
    y= 8/7 x-5/7
2. parallel means same slope, so your new equation will be y=8/7 x+b
3. To find the b, plug in your x and your y and solve for b
       2=8/7(-9)+b
       2=-72/7 +b
       2+72/7=b
       86/7=b
4. Now rewrite your equation.
      y= 8/7 x+ 86/7
weird looking, but I'm pretty sure it's right. (If  you divide out the sevens you get a whole ton of crazy decimals, so it's easier to leave it in fractional form).
