Answer:
(1,1)
Step-by-step explanation:
we have

we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
<u><em>Verify each ordered pair</em></u>
case A) we have
(5,0)
Substitute the value of x and y in the inequality

----> is not true
therefore
The ordered pair is not solution to the inequality
case B) we have
(0,-2)
Substitute the value of x and y in the inequality

----> is not true
therefore
The ordered pair is not solution to the inequality
case C) we have
(1,1)
Substitute the value of x and y in the inequality

----> is true
therefore
The ordered pair is a solution to the inequality
case D) we have
(-5,-6)
Substitute the value of x and y in the inequality

----> is not true
therefore
The ordered pair is not solution to the inequality
23.1/7= 3.3, So by this way we recognized that the small figure is 3.3 times smaller than big figure.
