Use the following lines to answer the question. line g: y=−45x+75 line h: y=54x+34 Is line g perpendicular to line h? Why or why not? No, because the slopes of lines g and h have different signs. Yes, because the slopes of lines g and h are opposite and reciprocal. Yes, because the slopes of lines g and h are opposite and the y-intercepts are different. No, because the y-intercepts of lines g and h are different.
