Number 17 is Infinity. I'm still working on the rest
(Y1-Y2)/(X1-X2)
(2-4)/(-2-3)
-2/-5
2/5
The sides of a right triangle can be found using the Pythagorean Theorem: a^2+b^2=c^2
c is the hypotenuse (the longest side) of the right triangle and a and b are the two other legs. Knowing any two sides of the right triangle, you can find the other using this formula.
Hope this helps!
72,429 rounded to the nearest ten-thousands is 70,000.
I think the answer is 17%
