For this case we have that by definition, the equation in the form of slope-intersection is given by:

Where 
Substituting the given point:  and the cutoff point
 and the cutoff point  we can find the slope,
 we can find the slope,
We have:


Thus, the equation is given by:

Answer:
X Coordinate. The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate.
