Answer:
Perpendicular line is y = -3/5 x - 20/3
Explanation:
First subtract 5x to move it to the other side. Now you have -3y = -5x + 20 . Next divide -3 on both sides to get y by its self. Now you have
y = 5/3 x - 20/3.
To find the perpendicular line, just remember that slope will be opposite. Look at the graph, I did for you above.⤴⤴⤴
