y = [___]x + [___]

Which lines are parallel to the graph of 4x – y = 6? Check all that apply.x – 4y = –12y – 2 = –4(x + 1)y + 1 = 4(x – 2)y = 4x + 11y = x – 38x – 2y = 6

The line y = –8 is [___].

Are the lines perpendicular?no, because the slopes of the lines are equalno, because the slopes of the lines are not opposite reciprocalsyes, because the slopes of the lines are equalyes, because the slopes of the lines are opposite reciprocals

Is triangle ABC a right triangle?no, because none of the slopes of the line segments forming the legs are opposite reciprocalsno, because none of the slopes of the line segments forming the legs are equalyes, because BC is perpendicular to ACyes, because AB is perpendicular to AC
