need help in finding the ordered pair for x+y=5

Question

i do not know how to work this problem

Answer 1

 

You can first solve for y:   y = -x + 5

 

Now you can pick values for x and compute the corresponding y value, each one of these (x,y) pairs is an ordered pair.

 

Examples:

x            y

—          ---

0            5     (0,5) is an ordered pair satisfying the equation

10          -5    (10,-5) is another ordered pair that satisfies the equation

20          -15   (20,-15)

 

x            -x+5  (x, -x+5)  is the general form for an ordered pair that satisfies the equation

 

If you graph y=-x + 5 you will  find it is a straight line, and the coordinates of any point on that line are an ordered pair that satisfies the equation.

 

 

 

Answer 2

The ordered pair? Do you have choices? 

 

(0,2)

 

0 + 2 = 5

2 = 5

0 = 3

 

Nope, not an ordered pair for the equation.

 

If you need to make one up, pick an x or a y.

 

x = 7

 

7 + y = 5

y = -2

 

(7,-2)
