Answer:
The equation x - y = 7 represents a linear equation with two variables, x and y. To find three ordered pairs (x, y) that satisfy this equation, we can arbitrarily choose values for one variable and solve for the other.
Ordered Pair 1:
Let's choose x = 0:
x - y = 7
0 - y = 7 (Substituting x = 0)
y = -7
So, the first ordered pair is (0, -7).
Ordered Pair 2:
Let's choose y = 0:
x - y = 7
x - 0 = 7 (Substituting y = 0)
x = 7
So, the second ordered pair is (7, 0).
Ordered Pair 3:
Let's choose x = 5:
x - y = 7
5 - y = 7 (Substituting x = 5)
y = -2
So, the third ordered pair is (5, -2).
Therefore, three ordered pairs (x, y) that satisfy the equation x - y = 7 are: (0, -7), (7, 0), and (5, -2).
