Answer: A.) It is a linear function because there is a constant rate of change in both the input and output values.
============================================================
Explanation:
Note how x is decreasing by 3 each time
- -2-3 = -5
- -5-3 = -8
- -8-3 = -11
At the same time, y is also decreasing by 3 each time
This means we have a linear function. We have,
slope = (change in y)/(change in x)
slope = (-3)/(-3)
slope = 1
Recall that slope is another term for rate of change, so a constant slope means we have a constant rate of change.
----------------
Another way to find the slope is to pick any two points from the table and use the slope formula
m = (y2 - y1)/(x2 - x1)
You should find that any two points you pick will lead to a slope of 1. I recommend you try out all possible pairs to help convince yourself the slope is 1.
Answer:
Step-by-step explanation:
1/3 of a mile in 15 minutes. 1.333 (4/3) miles an hour
18 Is the correct answer. Add up 22 and 14 and you get 36.54 minus 36 is 18.Hope this helps somehow.:)
One quarter is answer I think
The value is 20,000 because 2x10 equals 20, 20x1,000 equals 20,000
