Marque un punto y trace varias rectas que pasen por el.¿que concluye?

The generic equation of a line is:
 y-yo = m (x-xo)
 Where,
 (xo, yo): It's an ordered pair either.
 m: is the slope of the line.
 We observe that for a point (xo, yo) infinite lines with different slope m can pass.
 
 The conclusion is that for the ordered pair (xo, yo) can pass infinite lines that satisfy:
 y-yo = m (x-xo)

Iam not sure , but probably 750 or 7.5
