Answer 6

\[\frac{ y2-y1 }{ x2-x1 }\]
is the formula we use, just plug known points. Usually we use the origin (0,0) and a point along the line.

Answer 7

Alright, I'm new to this site. I'm sorry. So, what am I supposed to write?

Answer 8

from the pic, the line hits y=25 at x=3, so
\[\frac{ 25-0 }{ 3-0} = 25/3\]

Alright.. I think I get it. Thank you
