Answer:
[tex]-\frac{4}{5}[/tex]
Step-by-step explanation:
Since line e is perpendicular to line d, the slope for line e would be the inverse of line d.
Therefore, the slope of e would have to be [tex]-\frac{4}{5}[/tex].
When lines are perpendicular inverse the slope.
When lines are parallel the slope stays the same but the y-intercept changes.
I hope this helps!!
