Question 4 • Geometry with Statistics
Which statement is true about the graphs of the two lines y is equal to negative 4 fifths x plus 2 and y is equal to negative 5 fourths x minus 1 half ?
Answer
A
The lines are neither parallel nor perpendicular to each other because 2 and negative 1 half are not opposite reciprocals of each other.
B
The lines are neither parallel nor perpendicular to each other because negative 4 fifths and negative 5 fourths are not opposite reciprocals of each other.
C
The lines are perpendicular to each other because 2 and negative 1 half are opposite reciprocals of each other.
D
The lines are perpendicular to each other because negative 4 fifths and negative 5 fourths are opposite reciprocals of each other.
