The answer is B because if you have y = -2x + 4, to get the -2x to the same side as y, you need to add, making it y + 2x = 4. It would also be postive no matter what because this formula needs to be positive. ... and the standard form is Ax + By = C.. Making your final answer 2x + y = 4.
You can use the ASA postulate which means angle side angle. if 2 angles and the including side are congruent to the corresponding parts of another triangle then the triangles are congruent. hope that helps :)
