Answer 2

Answer:

The line can be defined as y = 25x.

Step-by-step explanation:

First we find two points that this falls on.  (0, 0) and (200, 8) clearly visible points that it falls on.  If we take common factors out of that, we get (1, 25).

With those points, we have the slope of the function.  Slope is equal to Δy/Δx, so in this case its 25/1 or just 25

Normally, to define a line, we would take a point on it and use it as reference, defining the line as (y - y1) = s(x - x1).  In this case though, because the line intersects point (0, 0), we don't even need to translate it.  We can simply say:

y = sx

We already have our slope of 25, so the our line function is:

y = 25x
