Calculate the slope − intercept form of the equation of line y 2 .

Answer to Problem 84E
The slope − intercept form of the equation of line is
Explanation of Solution
Given:
It is given in the question that the lines are perpendicular and the graph is given below.
Concept Used:
In this,use the concept that all the perpendicular lines have slopes that are the negative reciprocals and the slope intercept form
Calculation:
In this,it is known that the perpendicular lines have slopes that are the negative reciprocals.
Now,the equation of the first line is
So,the slope of this perpendicular line is
From the graph it is clearly seen that y 2 crosses the y −axis at
So,the equation of the line y 2 ,
Conclusion:
The equation of line is
