Question

practice & problem solving
in 13 - 20, graph and label each point.

1. a(1, - 1)
2. b(4, 3)
3. c(-4, 3)
4. d(5, - 2)
5. e(-2.5, 1.5)
6. f(2, 1.5)
7. g(-2, -1\frac{1}{2})
8. h(1\frac{1}{2}, - 1)

in 21 - 26, write the ordered pair for each point.

1. p
2. q
3. r
4. s
5. t
6. u

in 27 - 30, use the map at the right.

1. which building is located in quadrant iii?
2. which two places have the same x - coordinate?
3. use structure the city council wants the location of the entrance to a new city park to be determined by the reflection of the school entrance across the y - axis. what are the coordinates of the entrance to the new city park on this map?

Explanation:

Step1: Recall coordinate - plane rules

In a coordinate - plane, for a point $(x,y)$, $x$ is the horizontal (abscissa) and $y$ is the vertical (ordinate) value.

Step2: Graph point A(1, - 1)

Move 1 unit to the right on the x - axis and 1 unit down on the y - axis and label the point A.

Step3: Graph point B(4, 3)

Move 4 units to the right on the x - axis and 3 units up on the y - axis and label the point B.

Step4: Graph point C(-4, 3)

Move 4 units to the left on the x - axis and 3 units up on the y - axis and label the point C.

Step5: Graph point D(5, - 2)

Move 5 units to the right on the x - axis and 2 units down on the y - axis and label the point D.

Step6: Graph point E(-2.5, 1.5)

Move 2.5 units to the left on the x - axis and 1.5 units up on the y - axis and label the point E.

Step7: Graph point F(2, 1.5)

Move 2 units to the right on the x - axis and 1.5 units up on the y - axis and label the point F.

Step8: Graph point G(-2,-1.5)

Move 2 units to the left on the x - axis and 1.5 units down on the y - axis and label the point G.

Step9: Graph point H(1.5, - 1)

Move 1.5 units to the right on the x - axis and 1 unit down on the y - axis and label the point H.

Since the map for questions 21 - 30 is not fully visible, we can't answer those parts. But for the points 13 - 20, the points are graphed as described above.

Answer:

Points A - H are graphed as per the steps above.
