Answer 1

parallel lines are those with the same slope = 2/5

such as y=(2/5)x + b where b is any real number except 1

perpendicular lines are those with a slope that is the negative inverse, =-5/2

such as y =-(5/2)x + b where b is any real number

lines that are neither parallel or perpendicular are those with slope that is any real number except 2/5 or -5/2, such as y= mx + b where b is any real number, and m= any real number except 2/5 or -5/2

y=5x + 2
