The hight will be the difference in the y's of the points, and the length will be the difference of the x's of the points.
Using pythagorean theorm, you can then find the length of the hypotenuse, the segment connecting the points.
P(10, 7) and Q(1, 8)
change in y: 7 - 8 = -1
change in x: 10 - 1 = 9
Pythagorean theorm takes care of that negative since it squares both numbers, so I'll ignore that for now. we have:
1² + 9² = c²
1 + 91 = c²
c² = 92
c = 2√23

#2 is a horizontal line due to no change in y. subtract your x's.

answer:
27 years
step-by-step explanation:
let us assume that you was 18 years old when you graduated the high school.
the going on year is 2018.
you graduated the high school. in 2009.
so, 2018-2009 = 9 years ago you graduated the high school.
9 years ago you was 18 years old so now after 9 years you are 18+9 = 27 years old
so, you are 27 years old now .
