What linear function equation can be represented by the set of ordered pairs?
2 answers:
As set of four points are given.
First we will check whether these four points are collinear or not , i.e whether they lie in a line or not.
So plotting on the graph these four points, (−4,−6),(0,−3),(4,0),(12,6).
As you can see all these points are collinear.
So we can find the equation of line joining two points , (a,b) and (c,d) which is given by :
⇒
Select any two points among the given ordered pairs
By considering point (0,-3) and (4,0), we can get equation of line as follows

Answer:
The time interval when is at
The distance is 106.109 m
Step-by-step explanation:
The velocity of the second particle Q moving along the x-axis is :
So ; the objective here is to find the time interval and the distance traveled by particle Q during the time interval.
We are also to that :
between
The schematic free body graphical representation of the above illustration was attached in the file below and the point when is at 4 is obtained in the parabolic curve.
So, is at
Taking the integral of the time interval in order to determine the distance; we have:
distance =
=
= By using the Scientific calculator notation;
distance = 106.109 m
