I assume you are looking for the point of intersection, correct me if im wrong. To find the point of intersection you set the two graphs equal to each other.
x-4 = -2x+5
x=-2x+9
3x=9
x=3
To find the y-coordinate of this point simply substitute into one of the equations.
3-4=-1
so the point of intersection for these two lines is (3,-1)

???
What are the coordinate points for what value of he parameter? In a parametric equation (such as you have) the Y and y are the points and the x is a free parameter. By substituting a numerical value for x, you then calculate the (Y,y) point.

y=x-4
y=-2x+5
2y=x+1
x=2y-1 substitute into 1st equation
y=2y-1
-y=-1
y=1
1=x-4
5=x
So x=5, y=1
