Igot the wrong answer, does anyone know what the right answer is? a. the distance between two points b. the horizontal change compared to the vertical change between two points c. the ratio of the change in y to the change in x along the line

It should be C.

The slope formula using 2 point is

m = (y2 - y1) / (x2 - x1)

That's another way of saying C. The problem with B is that it is the upside down of what the slope actually is.

16

Step-by-step explanation:

We must find integers x, y with the most amount of prime divisors, not necessarily distinct, such that x + 3y < 1,000.

Obviously, this is achieved when the divisor is the least prime 2. So, we must find integers n, m such that

since , then n must be 9. For n=9 we find the greatest integer m such that  

and we find m=7

 and   ,  are the numbers we are looking for and the sum of their length is 9+7 = 16.

So, 16 is the maximum possible sum of the length of x and the length of y.
