Line g: y=−4/5x+7/5 line h: y=5/4x+3/4 Is line g perpendicular to line h? Why or why not? A. Yes, because the slopes of lines g and h are opposite and the y-intercepts are different. B. No, because the slopes of lines g and h have different signs. C. No, because the y-intercepts of lines g and h are different. D. Yes, because the slopes of lines g and h are opposite and reciprocal.
