: Hello,
At a total lost with this one.
Can you pls complete the given ordered pairs so that each ordered pair satisfies the given equiation?
(0, ),( ,0),(-6, ),( ,5),2x + 3y = 5
Thank you for your time in this matter.

You can put this solution on YOUR website! Can you pls complete the given ordered pairs so that each ordered pair satisfies the given equiation?
:
Once you understand this it will be easy for you to do:
:
(0, ),( ,0),(-6, ),( ,5), 2x + 3y = 5
:
In the first ordered pair the give x = 0, want you to find y:
In the equation 2x + 3y = 5, replace x with 0 and solve for y:
3(0) + 3y = 5
0 + 3y = 5
y = 5/3
So the 1st ordered pair: (0,5/3)
:
On the 2nd ordered pair: (_,0), exchange 0 for y in the equation:
2x + 3(0) = 5
2x + 0 = 5
x = 5/2
The 2nd ordered pair: (5/2,0), in decimal it would be (2.5,0)
:
The 3rd ordered pair (-6,_), substitute -6 for x, find y:
2(-6) + 3y = 5
-12 + 3y = 5
3y = 5 + 12
3y = 17
y = 17/3 or decimal 5.67
The 3rd ordered pair (-6,5.67)
:
The 4th ordered pair: (_,5), Substitute 5 for y and find x:
2x + 3(5) = 5
2x + 15 = 5
2x = 5 - 15
x = -10/2
x = -5
The 4th ordered pair: (-5,+5)
:
Do you get the idea now?
