22. Point G is the point (3, -1). Which point is 5 units from Point G?__B (-2,-1)___________ 23. Label the coordinate plane then locate and label the set of points below. { (0.4, 35), (-0.5, 30), (0.3, 15), (-0.2, -10), (0.2, -5)}

Find the lengths of the line segments whose endpoints are given below. Explain how you determined that the line segments are horizontal or vertical. 24. (-5, 6) and (-5, 13) Both endpoints have x-coordinates of -5, so the points lie on a vertical line that would pass through -5 on the x-axis. │6 │ = 6 and │13│ = 13, and the numbers are on the same side of zero. By subtraction, 13 – 6 = 7, so the length of the line segment with endpoints (-5, 6) and (-5, 13) is 7 units. 25. (9, -2) and (9, -15) Both endpoints have x-coordinates of 9, so the points lie on a vertical line that would pass through 9 on the x-axis. │-2 │ = 2 and │-15│ = 15, and the numbers are on the same side of zero. By subtraction, 15 – 2 = 13, so the length of the line segment with endpoints (9, -2) and (9, -15) is 13 units. 26. (-1, 0) and ( 10, 0) Both endpoints have y-coordinates of 0, so the points lie on x-axis. │-1 │ = 1 and │10│ = 10, and the numbers are on the opposite side of zero so their absolute values must be added. By addition, 1 + 10 = 11, so the length of the line segment with endpoints (-1, 0) and ( 10, 0) is 11 units. 27. The coordinates of point A are (-6, 4). The coordinates of point B are (3, 4). Which expression represents the distance in units between points A and B? c. │-6│ + │-4│ a. │-6│ + │3│ b. │3│ - │-6│ d. │4│ - │-6│ 28. Two of the vertices of a rectangle are (2, -6) and (8, -6). If the rectangle has a perimeter of 30 units, what are the coordinates of its other two vertices?

29. A rectangle has a perimeter of 24 units, an area of 36square units, and sides that are either horizontal or vertical. If one vertex is the point (-2, -3) and the origin is in the rectangle, find and label the other vertices of the rectangle. What is the coordinate in quadrant II? 30. Graph a rectangle with area 14 units2, such that its vertices lie in at least two of the four quadrants in the coordinate plane. List the lengths of the sides, and use absolute value to show how you determined the lengths of the sides. answers will vary sides may be: 14 by 1 or 7 by 2
