They have no relation, except for the fact that they intersect.
We have given that,
The graphs of the two lines y= -4/5x + 2 and y = - 5/4x - 1/2
If the equations were instead y = +5/4x - 1/2 and
<h3>What is the slope of the perpendicular line?</h3>
Vertical lines and horizontal lines are perpendicular to each other. The slope of the perpendicular line in this case would be the slope of a horizontal line which would be 0. The slope of the parallel line is undefined and the slope of the perpendicular line is 0.
y = -4/5x + 2, or
y = +4/5 + 2 and
y = -5/4x -1/2,
Then they would be perpendicular.
