A table pairs x-values 2, 5, and 8 with y-values 6, 15, and 24. Is y directly proportional to x?
No, because the x-values do not rise by equal amounts.
Yes, because y divided by x is always 3.✓پاسخ درست
No, because y rises by different amounts each time.
Yes, because every y-value is larger than its x-value.
توضیح
The quotients are 6 divided by 2, 15 divided by 5, and 24 divided by 8, all equal to 3, so the table follows y equals 3 times x. Equal increases are not required: the input gaps differ, but the constant output-to-input ratio establishes direct proportion.
