Question

Answer 1

Ordered pairs are listed as (x, y). Your ordered pairs are (x, -10), (x, 7) and (2, y).

 

Plug in the known value of x or y for each ordered pair in the equation 5x - 2y = -10 to find the missing value in the ordered pair.

 

For example, for ordered pair (x, 7), in equation 5x - 2y = -10, substitute 7 for y.

 

5x - 2 * 7 = -10

 

5x -14 = -10

 

5x - 14 +14 = -10 + 14

 

5x = 4

 

5x /5 = 4/5

 

x = 4/5

 

So ordered pair is (4/5, 7).

 

You can do the rest of ordered pairs yourself.
