The line equation in slope-intercept form is , where m is the slope

and b is the y-intercept.

Find the slope of the equations.

Slope of the first equation is .

Slope of the second equation is 5.

If two lines are parallel, their slopes must be equal. (Or)

If two lines are said to be perpendicular,the product of their slopes is equal to .

Here in this case,the two slopes are neither equal nor their product is equal to .

The lines are neither parallel nor perpendicular.
