You can put this solution on YOUR website! Complete the ordered pair for the equation 2x + y = 10. (5, ), ( , 10), ( , -2), (0, ).
----------------
You are given a rule that relates x and y.
Substitute the x or y value you are given in each
ordered pair and solve for the unknown value, as follows:
-----------
2x+y=10
(5, )
You are told that x=5 and are asked to find the y value.
Substitute the 5 into the rule and solve for y as follows:
2(5)+y=10
10+y=10
y=0
Ans: (5,0)
-----------------
2x+y=10
( ,10)
You are told that y=10 and are askied to find the x value.
Substitute 10 into the rule and solve for x as follows:
2x+10=10
2x=0
x=0
Ans: (0,10)

Hope this helps.
