Concept explainers
To calculate : The given lines are parallel, perpendicular, or neither.
Answer to Problem 19OE
The given lines are parallel because both the lines have same slope.
Explanation of Solution
Given information : Given equations are:
Formula used : Slope intercept form is given by
Where,
The two lines are parallel if they have the same slope.
The slope of perpendicular lines is negative reciprocal of each other.
Calculation : Compare both the equations with
The slope of equation
Solve for
The slope of equation
So, both the lines are parallel.
