Laura says that there are two points on the coordinate grid that are the same units to the right of 0. What are they?


a.
B and C
b.
A and B


Solution:

Points B and C are the same units to the right of 0.
[Each point is 3 units to the right of 0.]


Correct answer : (1)
 82.  
Which ordered pair gives the location of point B?


a.
(3, 4)
b.
(3, 2)
c.
(4, 3)
d.
(4, 4)


Solution:

Point B is 3 units to the right of 0 and 4 units up from 0.

So, (3, 4) is the ordered pair for the point B.


Correct answer : (1)
 83.  
Which ordered pair represents the point N?


a.
(2, 2)
b.
(6, 6)
c.
(1, 6)
d.
(6, 1)


Solution:

Point N is 6 units to the right of 0 and 1 unit up from 0.

So, (6, 1) is the ordered pair for the point N.

 84.  
Which statement is true?

a.
(4, 3) is the ordered pair for the point B
b.
(3, 2) is the ordered pair for the point C
c.
A, B and C are collinear
d.
Points B and C are on the same horizontal line


Solution:

Consider each statement one by one.

Points B and C are on the same horizontal line.
[Consider statement 1.]

Statement 1 is false.
[Points B and C are on the same vertical line.]

(3, 2) is the ordered pair for the point B.
[Consider statement 2.]

Statement 2 is false.
[(3, 4) is the ordered pair for the point B.]

(2, 3) is the ordered pair for the point C.
[Consider statement 3.]

Statement 3 is false.
[(3, 2) is the ordered pair for the point C.]

(3, 2) is the ordered pair for the point C.
[Consider statement 4.]

Statement 4 is true.

Find the coordinates of the point S in the graph.

a.
(6, 6)
b.
(6, 4)
c.
(5, 4)
d.
None of the above


Solution:

Start at the origin.

Move 6 units to the right from the origin.

The first coordinate is 6.

Then move 4 units up from the x-axis.

The second coordinate is 4.

The coordinates of point S are (6, 4).

 86.  
A star pattern has some points marked on it. Find the coordinates of the points D, E and F.


a.
D(0, 2), E(0, 3) and F(4, 3)
b.
D(3, 3), E(3, 3) and F(1, 2)
c.
D(2, 1), E(5, 3) and F(8, 1).
d.
D(1, 2), E(2, 3) and F(4, 5)


Solution:

D is 2 units to the right from the y-axis and 1 unit up from the x-axis.

So, the coordinates of D are (2, 1).

E is 5 units to the right from the y-axis and 3 units up from the x-axis.

So, the coordinates of E are (5, 3).

F is 8 units to the right from the y-axis and 1 unit up from the x-axis.

So, the coordinates of F are (8, 1).

The following map is a part of the XYZ Airline's top US domestic markets in a coordinate system. Between which sections is Las Vegas located?

a.
B1and C1
b.
B3 and C3
c.
B2 and C2
d.
None of the above


Solution:

Move to the second row B in the map.

Move to the right till column 3.

This is the section B3 where a portion of Las Vegas is located in the same column at the border.

Move downwards in the same column till row C.

This is the section C3 where the other portion of Las Vegas is located at the border.

So, B3 and C3 are the sections between which Las Vegas is located.

 88.  
The following map is a part of the ABC Airlines' top 10 domestic passenger markets in a coordinate system. Between which two sections is Orlando located in the map?

a.
A2 and B2
b.
C2 and C3
c.
B2 and C2
d.
B3 and C3


Solution:

Move to the second row B in the map.

Move to the right till column 2.

This is the section B2 where a portion of Orlando is located at the border.

Move downwards in the same column till row C.

This is the section C2 where the other portion of Orlando is located at the border.

B2 and C2 are the sections between which Orlando is located.


Correct answer : (3)
 89.  
The following map is a part of the ABC Airlines' top 10 domestic passenger markets in a coordinate system. In which section are most of the places located in the map?


a.
C4
b.
B3
c.
A2
d.
C2


Solution:

There are 6 places namely Atlanta, Tampa, Orlando, West Palm Beach, Fort Lauderdale and Miami located in the map.

In between the sections A1 and A2, Atlanta is located.

Tampa is located in the section C2.

In between B2 and C2, Orlando is located.

West Palm Beach is located in the section C2.

Fort Lauderdale is located in the section C2.

Miami is located in the section C2.

So, section C2 has the maximum number of places located in the map.
