The answer is $-10$ . Explanation below.

First, substitute the values $2$ for $x$ and $5$ for $y$ :

$(5 - (-5))/(2-3)$

Recall that $a - (-b) = a + b$

$(5 + 5)/(2-3) = 10/(-1) = -10$ .

See the entire evaluation process below:

To evaluate this expression substitute $color(red)(2)$ for $color(red)(x)$ and $color(blue)(5)$ for $color(blue)(y)$ :

$(color(blue)(y) - (-5))/(color(red)(x) - 3)$ giving:

$(color(blue)(5) - (-5))/(color(red)(2) - 3)$

Next, rewrite the numerator of this expression to eliminate the double negative sign. Remember, $color(blue)(- - = +)$

$(color(blue)(5) + 5)/(color(red)(2) - 3)$

Now we can complete the evaluation:

$10/-1 -> -10$
