Slope = (y2 - y1) / (x2 - x1)
(-1,3)....x1 = -1 and y1 = 3
(1,-1) ...x2 = 1 and y2 = -1
now we sub
slope = (-1 - 3) / (1 - (-1) = -4/2 = -1/2 <==
The greatest number of xs all the terms have in common is 1x
Yep! The answer is 9
When using the Pythagorean theroem, you use a^2+b^2=c^2
Because c represents the hypotenuse, c=15
and a=12
12^2+b^2=15^2
144+b^2=225
b^2=81
b=9
I hope this helps!
