Each ordered pair is simply (x,y). For instance, (0,4) can written as x=0 and y=4.
So to see if the solutions work, plug them into the equation


check to see if 1st pair works
false


check to see if 2nd pair works
true


check to see if 1st pair works

false (edit: sorry I read the problem wrong)
So only (4,0) is the only solutions.

Determine if the ordered pair is a solution of the equation
3x-y=12
Substitute the x and the y values into the equation to see if you get a true statement:
(0,4): 3*0-4=12; -4=12; not true so pt is not a solution.
(4,0): 3*4-0=12; 12=12; true so pt is a solution
(-1,15): 3*-1-15=12; -3-15=12;-18=12; falso so pt is not a solution
