Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
The slope formula of the line that pass across two points P1(x1,y1) and P2(x2,y2) is:
You can use this formula to solve all the four points:

The Answer is A.
Repeating number is not a function. It's ok to have repeating number in Y or the range but not the X which is the Domain.
Mean: 10.5
Median: 10.5
Range: 5
--------------------------------------------
<u></u>
To find the mean you order the numbers then add then divide.
<u>Add</u>
8+9+10+10+10+11+11+11+12+13=105
<u>Divide</u>
105÷10=10.5
Mean = 10.5
--------------------------------------------
<u></u>
Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.
Find the middle number. Put your left finger on 8 and your right finger on 13. Move your left finger to the right to 10 and move your right finger to 11.
the middle number is 10.5 so therefore it is the median.
--------------------------------------------
<u></u>
To find the range you subtract the biggest number to the smallest number.
<u>Subtract</u>
13-8=5
Therefore 5 is the range
C=90°
Since the triangles are similar, the angles will be the same. A corresponds with D and equals 75° and B corresponds with E and equals 15°, so C and F must be 90°, since the angles in a triangle add up to 180°.
Hope this helps :)
