All right triangles are : 1. perpendicular
2. congruent
3. supplementary
4. corresponding

I think that it’s A, Perpendicular (correct me if I’m wrong)

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

The difference is 5,100m?
