Answer:
-2
Step-by-step explanation:
From the ratio computed, the numbers will be 420 and 980.
<h3>How to calculate the ratio</h3>
From the information given, we are to divide 1400 in the ratio 7:3. The smaller number will be:
= 3/(3+7) × 1400
= 3/10 × 1400
= 420
The larger number will be:
= 7/10 × 1400
= 980
Therefore, the numbers will be 420 and 980.

<em>Because OP only asked for a clarification of the problem statement: </em>
You are asked to find the green area. (Hint: divide the green area into rectangles and right triangles, because you know their area.)
Answer: 2: an equation in the form y = mx + b
1. An x/y table may have two entries with the same x; not a function in that case.
2. That's a line with a slope; for each x there's a single y, definitely a function
3. Ordered pairs -- like the table, the same x with different ys is possible, which wouldn't be a function.
4. List of numbers -- a list isn't a function, at least not without more context
