Can anyone answer the 7th and 8th question for

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Which equation is represented by the graph below?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
