The number of two of the nine members of ski patrol unit can be chosen is equal to the combinations of 9 taken 2. This can be calculated using the formula:

$\frac{9!}{2!*(9-2)!}$

= $\frac{9!}{2!*7!}$ , where

9! =9×8×7×6×5×4×3×2×1 and

7!=7×6×5×4×3×2×1

2!=2×1 then the equation becomes:

= $\frac{9*8}{2}$ =36

Using the slope formula, determine the slope of the two points.

Lelechka [254]

The slope formula is is rise over run or y2-y1/x2-x1

If you plug in those numbers you will get

(-1)-(-4)
———
1-(-2)

Simplify it and you get

3
— or 1
3

So the slope is 1
