Line BC has an equation of a line y = 2x + 3, and line EF has an equation of a line y = โˆ’3x + 4. These two equations represent..?

A) parallel lines because the slopes of the lines are the same
B) perpendicular lines because the product of the slopes is โˆ’1
C) the same line
D) lines that are neither parallel nor perpendicular

Thanks!
