ANSWER
(-1,5)
(7,5)
EXPLANATION
The given set of parametric equations is:
and
We make t the subject in the first equation to get:
We put this into the second equation to get;
When x=-1,
Therefore (-1,5) lies on this line.
When x=7,
Therefore (7,5) also lie on this line.
The correct options are:
A. The scatter plot has an outlier at (15, 2)
B. The scatter plot has a cluster with a range from 2 to 4
<u><em>Explanation</em></u>
Co ordinate of any point can be written in form of (x,y) where first value is the distance across x-axis and second value is the distance across y-axis.
We can see in the plot, that the outlier point is 15 unit across x-axis and then 2 unit across y axis from the origin. So the co ordinate of that point will be (15, 2).
Range means the values across the y-axis. We can see that the cluster starts at y=2 and ends at y=4. That means, the scatter plot has a cluster with a range from 2 to 4.
