y=5/3x=+6 and y=-5/3x are they parallel or perpendicular lines

Question

are these equations parallel or perpendicular lines

 

Answer 1

Sandee,

 

I assume the equations are

 

y = (5/3)x + 6 and y = -(5/3)x

 

These are neither parallel or perpendicular.

 

Slope of eq 1 is 5/3, slope of eq 2 is -5/3

 

For parallel lines slope should be same

Fro perpendicular limes product of slopes is -1
