Answer:
a. y = -5x
Step-by-step explanation:
The different signs of x and y tell you the constant of proportionality will be negative (eliminating choices <em>b</em> and <em>d</em>).
A quick trial of the given values shows that choice <em>c</em> is incorrect, and that choice <em>a</em> is correct.
200 can be rounded down to 200, which is easy to add with. Thus, an estimate is 222+200=422.
Alternatively, you could round 222 up a bit, to get 225+200=425. This is actually the correct answer, but this rounding doesn't make the calculation easier, so if you needed a quick estimate I'd go with the first option.
