Check Your Understanding Section 1.1

1. The point (−5,0) is on an axis, so it is not in any quadrant.
   The statement is false.
2. The ordered pair (1,−6) is located 1 unit right of the origin
   and 6 units below it. The ordered pair (−6,1) is located 6
   units left of the origin and 1 unit above it. Thus, (1,−6)
   and (−6,1) do not name the same point. The statement
   is false.
3. True; the first coordinate of a point is also called the
   abscissa.
4. True; the point (−2,7) is 2 units left of the origin and
5. units above it.
6. True; the second coordinate of a point is also called the
   ordinate.
7. False; the point (0,−3) is on the y-axis.
   Exercise Set 1.1
8. Point A is located 5 units to the left of the y-axis and
9. units up from the x-axis, so its coordinates are (−5,4).
   Point B is located 2 units to the right of the y-axis and
10. units down from the x-axis, so its coordinates are (2,−2).
    Point C is located 0 units to the right or left of the y-axis
    and 5 units down from the x-axis, so its coordinates are
    (0,−5).
