Concept explainers
a.
Calculate the slope and y − intercept (if possible) for the linear equation.
a.
Answer to Problem 46E
The slope of the equation is undefined and there is no y - intercept.
Explanation of Solution
Given:
It is given in the question that the equation is
Concept Used:
In this we have to keep some concept in mind:
(i) The graph of
(ii)Slope intercept form :
(iii)
(a)If
(b)If
(c)If
(d)If m is undefined, the line is vertical.
Calculation: The given equation is,
Since there is no y − value,this equation does not intersect with the y − axis.The only way this can happen is if the line is parallel to the y − axis.
Here it has to be seen that , the slope is undefined and there is no y - intercept..
Conclusion:
The slope is undefined and there is no y - intercept.
b.
Sketch the line by hand and by using the graphing utility.
b.
Explanation of Solution
Given:
It is given in the question that the equation is
Graph:
Interpretation:
The equation
So to draw this, pick a few y − values like
