Answer
Option C ,D and E
Explanation
Any time we divide an inequality by a negative number, we reverse the sign
The first error is that,
She did not change the sign > to <
Another mistake is that, she divided one side by -5 and multiplied the second by -5
Also whenever an inequality involve < or > we use an open circle on the number line.
So another mistake is that,
She used a closed circle instead of an open circle on the number line
The correct thing should have been
[tex]-5x-3.5\:>\:6.5[/tex]
[tex]-5x\:>\:10[/tex]
[tex]x\:<\:-2[/tex]
The number line is shown in the attachment.
