whether the graphs of the two equations are parallel, perpendicular, or neither.
Answer to Problem 28CR
The graphs of the two equations are parallel
Explanation of Solution
Given information: The two equations are
Consider the equation
This equation is in slope intercept form
So,
Slope of the line
Now consider the equation
First convert this equation in slope intercept form.
So,
Compare this equation with
So, slope of the line
Therefore,
Slope of the line
Use the fact that two lines are said to be parallel if their slopes are equal.
So,
The graphs of the two equations are parallel
