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

Answer to Problem 81E
The slope − intercept form of the equation of line is
Explanation of Solution
Given:
It is given in the question that the lines are parallel and the graph is given below.
Concept Used:
In this,use the concept that all the parallel lines have the same slope and the slope intercept form
Calculation:
In this,it is known that the parallel lines have the same slope
Now,the equation of the first line is
So,the slope of this line is
From the graph it is clearly seen that y 2 crosses the y −axis at 1.
So,the equation of the line y 2 ,
Conclusion:
The equation of line is
