Answer:

-1

Step-by-step explanation:

Use the rule y2-y1 / x2-x1

y1 = h

y2 = 9

x1 = -9

x2 = -8

so you get

9-h / (-8) - (-9) = 10

cross multiply to get

9-h = 10

so -h = 10-9

so h = -1

well, p + (-2), now a sign in front of a grouping symbol usually means it has a 1*, so +(, really means +1*, thus p + (-2) really means p + 1*(-2), which gives us p - 2, and that'd be ordinally, 2 numbers to the left of "p".

likewise, 5 + p, is just the same as p + 5, so that value will be a number 5 numbers to the right of "p".

just as above, p + 1, is just one value to the right of "p".

$\bf \rule[0.35em]{2em}{0.25pt}\stackrel{p-2~\hfill }{|\rule[0.35em]{2em}{0.25pt}}|\rule[0.35em]{2em}{0.25pt}\boxed{P}\stackrel{~\hfill p+1}{\rule[0.35em]{2em}{0.25pt}|}\rule[0.35em]{2em}{0.25pt}|\rule[0.35em]{2em}{0.25pt}|\rule[0.35em]{2em}{0.25pt}|\stackrel{~\hfill p+5}{\rule[0.35em]{2em}{0.25pt}|}\rule[0.35em]{2em}{0.25pt}|$
