Answer:

Yeah, it tells you values from when x and y are both -2, so I don't know why you need us to tell you.

Step-by-step explanation:

If you meant to ask something else, the way to find an X value is

Y = -0.5555555555555556 X — 0.3333333333333335

Just plug in x, and you'll get Y.

Answer:

The correct answer is C.

Step-by-step explanation:

The price of a four-star meal, only $50 per couple decades ago, has since increased 400%.

This means that if the $50 per couple is 100%(decimal 1), the current price is 100%+400% = 500%(decimal 5). So we can solve a rule of three to find the current price of a four-star meal.

1 - 50

5 - x

$x = 50*5$

$x = 250$ .

The current price of a four star meal is $250 per couple.

The correct answer is C.
