They are the coordinates of the infinitely many points on the line defined by the equation.
These are equations of two straight lines. Provided the equations are not of the same or parallel lines, there can be only one ordered pair. So the ordered pair is - not are : (0.5, -1)
The lines intersect at (3, 5)
This just means to list values of x and then plug them into the equation to find the value of y for that x. so in (x,y) form:(1,8) (2,16) (3,24) and so on.
X= -1/4. Y= -2/5. ( -.25, -0.4 )
