Question 1066527
.
-2=-11/3(4) + b solve for b

My answer I get is b= -46/3, but when I entered the problem in WolframAlpha, they got b=38/3. I just want to know where I went wrong.


Here's mine:

<pre>
       y=-11/3x+b
      -2=-11/3(4)+b
      -2=-44/3+b
      -b      -b
      -2-b=-44/3
       +-2    +-2       <<<---+++   I do not understand this "+-". Only "+" must be.
       b=-44/3+-2       <<<---+++   This line is INCORRECT.  As a consequence, the next line is incorrect, too.
       b=-46/3

Can you show me where I went wrong?
</pre>

Why it was so difficult to you to check it on your own ??
