Incorrect, she should have divided both sides by 8. The answer should be x=7. There is only 1 solution to the equation because x is raised to the first degree. It is not a polynomial equation so there won't be more than 1 answer to the equation.
The answer is A because using the point slope formula y-y1=m(x-x1) you get the answer choice A
