Antonia is biking 120 miles on a mountain bike her bike has a odometer that tells her how far she's gone as well as a timer which tells her how long she's been riding the first 3 hours of riding are over very difficult terrain and she only covers 30 miles

Aline is perpendicular to another line m2= (-1/m1), where m1 is the slope of the original line and m2 is the slope of the perpendicular line. which of the following equations represents the line that passes through the point (-2,1) and is perpendicular to the line below?
