Answer:
slope = -2
Step-by-step explanation:
Slope formula: 
Given points:
(3 -4) = (x1, y1)
(-2, 6) = (x2, y2)
To find the slope, input the given points into the slope formula:
Solve:
6 - (-4) = 6 + 4 = 10
-2 -3 = -5
Simplify:
The slope is -2.
The 9th student is in the middle.
⇒ There are 8 students before him
⇒ There are 8 students behind him
Total number of students = 8 + 1 + 8 = 17
Answer: 17
Find X:
38=(3x+4)+(5x-6)
combine like terms
38=8x-2
add 2 to both sides
40=8x
divide both sides by 8
5=x
Find AB:
16=3x+4
subtract 4 from both sides
12=3x
divide by 3
4=x
Find BC:
16=5x-6
add 6 to both sides
22=5x
divide both sides by 5
