Todetermine if the given lines are parallel, perpendicular or neither.
Answer to Problem 7CYU
The given lines are parallel.
Explanation of Solution
Given information :
W(-7, 6), X(-6, 9), Y(6, 3), Z(3, -6)
Slope of the line is given by the formula,
We know when the lines are perpendicular to each other than the product of their slope is equal to -1.
Hence the slope of line WX is,
The slope of the line YZ is,
Therefore the slope of the both the lines are same.
When the slope of two lines is same then the lines are parallel.
Hence the given lines are parallel.
