Answer:
A: (-7, 4)
B: (-6, -4)
C: (0, -3)
D: (2, 0)
Step-by-step explanation:
The first number in an ordered pair is the x point, so which number the point aligns with on the horizontal line.
The second number in an ordered pair is the y point, so which number the point aligns with on the vertical line.
If you look at point B you can see that it is directly below the -6 on the horizontal line and directly left of the -4 on the vertical line.
This means that point B is at (-6, 4)

A clock is a circle which is 360 degrees.
There are 12 hours -----> 360/12 = 30 degrees.
Going clockwise, add 30 degrees for every hour the hour hand is at.
There are 60 minutes -----> 360/60 = 6 degrees.
Add 6 degrees for every minute the minute hand is at.
Find position of both hour hand and minute hand, then take the difference.
Time is 5:15.
Hour hand is at 5 plus 15/60 or 5.25.
Multiply by 30. 30*5.25 = 157.5
Minute hand is at 15.
Multiply by 6. 15*6 = 90
157.5 - 90 = 67.5 degrees.
