Answer :

Answer:

Red line slope = - [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

We know

- The lines are perpendicular.

- The green line has a slope of [tex]\frac{2}{5}[/tex].

What is the slope of the red line?

If the green line is perpendicular to the red line, then their slopes are negative reciprocals of each other.

Red line slope = - [tex]\frac{5}{2}[/tex]
