Consider the line y=5/4x

Answer 1

As a straight line, it should be written as y=5x/4 or y= (5/4)x

It's a line with slope = 5/4 with y intercept = 0 or the point (0,0), the origin. The x intercept is also the same point, the origin.

If you write y = 5/4x that really means y = 5/(4x) or xy=5/4, which is not a straight line, but a rectangular hyperbola, with two separate branches in quadrants I and III.
