Explanation of Solution
Given information :
the set of data
figure : Now plot the each point in a coordinate plane as shown in the figure.
Interpretation: from the figure it can be observed that the data is approx. linear.
b.
To draw : the line that passes through two of the points.
b.

Explanation of Solution
Given information :
the set of data
Graph : joint the two points like
So the line in the scatter plot can be obtained as:
Interpretation:from the above graph it can be observed that the line passes through the points
c.
To find : the equation by using two points.
c.
