40 Point Question What is the difference between the slopes of x = 5 and y= -6? y = -6 is a horizontal line, which means the slope is zero. x = 5 is a vertical line, which means the slope is undefined Back to the Game Board

10 Point Question What is the slope of a line that is parallel to the graph of -4x + 3y = 7? 4/3 Back to the Game Board

20 Point Question The graph of the line through (2,3) that is perpendicular to the line with equation x = -1 also goes through which point? a) (0,-1)b) (-2, 3) c) (2, -4)d) (1, 4) B. Note: the slope of x = -1 is zero. The inverse is undefined, therefore the line is vertical. Back to the Game Board
