The prime factorization of 18 is: 2 x 3 x 3.
The prime factorization of 45 is: 3 x 3 x 5.
The prime factors and multiplicities 18 and 45 have in common are: 3 x 3.
3 x 3 is the gcf of 18 and 45.
gcf(18,45) = 9.

Answer:
y = 3
Step-by-step explanation:
Use the slope formula:
y2 - y1
m = ------------- , which here becomes
x2 - x1
y - 5 -1
m = ------------- = -----
8 - (-2) 5
Solve this for x. Cross multiplication yields:
5y - 25 = -1(10) = -10
Then 5y = 15, and y = 3
