Equations of Parallel and Perpendicular Lines
Question 1 of 10 • TX-Algebra I A-CR
Which statement is true about the graphs of the two lines y = –6 and x = ?
Answer
A
The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = is a vertical line with a slope of 0.B
