Answer:
the answer is two points determine a unique line segment

The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
(3 , -1)
Step by step explanation:
On the x-axis, the dot is below the number 3 and on the y-axis, the dot is on the right side of -1
They could have 10 hotdogs which equals $7.50 and 3 drinks which equals $4.50. $7.50+$4.50 = $12
I think it’s the one on the bottom left
