C
Step-by-step explanation:
Answer: Choice C
(4, 18)
=========================================
Explanation:
One point shown on the graph is (2,9)
If we double each x and y coordinate, then
We go from (2,9) to (4,18)
Plotting this point on the graph will be on the same line as the other points.
Or you could note that y/x = 9/2 = 18/4 = 4.5
Let's say the least amount of money is "x", therefore whatever "x" is, it has to be "greater than or equals to 500", thus x ⩾ 500.
so, let's add "x" to the current balance including debts.
You could model a present by shading in squares on a 10 by 10 grid
