Answer:
<h2>YES. These points are collinear.</h2>Step-by-step explanation:
If three points are collinear, then the slopes are the same.
The formula of a slope:
For (0, -10) and (-3, -13):
For (-3, -13) and (2, -8):
We can check the last pair (0, -10) and (2, -8):
Given:
The equations are
To find:
Which function is changing more quickly.
Solution:
The slope intercept form of a line is
Where m is slope and b is y-intercept.
On comparing with the slope intercept form, we get
On comparing with the slope intercept form, we get
Since, , it means the absolute rate of change of second function is greater than the first function.
Therefore, the second function is changing more quickly.
