The following two lines are perpendicular to each other. . 2 , 5 6 and 6) (4, through passes : Line 5 5 2 : Line 2 1 = +L y x L III. A line through (3, 4) and (3, 5) is a horizontal line. IV. The line 2 2= x y rises to the left. V. The point (1, 3) is a point in the solution set of x > 0 and ≤ y . Example 6: Which of the following are false ? I. The slope of the line through (3, 2) and (5, 2) is undefined. II. The point , 4 5 is on the graph of . 5 7 4y x III. Line 1 L has slope m . Line 2 L is parallel to line 1 L , so 2 L has slope m. IV. The point (1, 2) is in the solution set of 1x y . V. The solution to 4 3 2 ≥y x is the halfplane lying below the line 4 3 2 =y x ....
