Answer:
choice 2) 4/3πr³
Step-by-step explanation:
If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.
An example of the equation would be
y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept
The average rate between two points is calculated the same way you would calculate the slope of a line (rise/run).
96-36/8-3
= 60/5
= 12
67 is the answer to the question
