Which statement is true about the graphs of the two lines y = -4/5 x + 2 and y = -1/2x ? 1. the lines are perpendicular to each other because -4/5 and -5/4 are opposite reciprocals of each other. 2. the lines are perpendicular to each other because 2 and -1/2 are opposite reciprocals of each other. 3. the lines are neither parallel nor perpendicular to each other because -4/5 and -5/4 are not opposite reciprocals of each other. 4. the lines are neither parallel nor perpendicular to each other because 2 and -1/2 are not opposite reciprocals of each other.
