Question 106438: Which of the ordered pairs (0,0)(-2,10)(-1,-5)(-3,9)are the solutions for the equation y=5x? I don't know if I did these right?
y = 5(x)
0 = 5(0)
0 = 0 not a solution
-2=5(10)
-2 = 50
y = -25 yes, is a solution
-1 = 5(-5)
y = -25 yes, is a solution
-3= 5(9)
-3 = 45
y = 15 yes, is a solution
Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Remember the ordered pair is given in terms of (x,y).
Once you substitute for x and y, you should no longer have any sentence with x and y in them, only numbers.
Let's look at your first answer (x,y)=(0,0).
Original equation.
Substitute the values.

This ordered pair leads to a true statement.
Therefore the ordered pair is a solution to the problem.
Second pair (x,y)=(-2,10).



Since this ordered pair leads to a false statement,
it is not a solution to the problem.
Once you substitute for x and y, you should no longer have any sentence with x and y in them, only numbers.
Third answer (x,y)=(-1,-5)



True statement, a solution to the problem.
Fourth and final,(x,y)=(-3,9)



False statement, not a solution to the problem.
Hope it helps and good luck.
