Note that
a. When two lines are parallel, their slopes are equal.
b. When two lines are perpendicular, the product of their slopes is -1.
c. A vertical line has undefined slope.
d. A horizontal line has a slope of zero.
The two slopes are 5 and 1/5.
The product of the slopes is 5*(1/5) = 1.
Test the given answers.
Neither line is vertical because each line has a defined slope.
The lines are not parallel, cause their slopes are not equal.
The lines are not perpendicular because the product of their slopes is not equal to -1.
Answer: None of these
