Answer:
1/2
Step-by-step explanation:
Pick two points on the line
(2,0) and (4,1)
Use the slope formula
m= (y2-y1)/(x2-x1)
= (1-0)/(4-2)
= 1/2
Answer:

Step-by-step explanation:




Answer: the last one
Step-by-step explanation: because 7 times 24 equals 168 and x would be 21 so 21 times 8 equals 168.
The average value over the interval is the area under the curve divided by the width of the interval.
Area = 4*(6 -1) +5(8 -6) = 30
Width = 8 - 1 = 7
Average value = 30/7 = 4 2/7
If by description you mean simplification then: 84x/28
