Afigure has a vertex at (-1, -3). if the figure has line symmetry about the y-axis, what are the coordinates of another vertex of the figure?

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
