So,
To find the GCF, you have to factor all of the numbers.
21 --> 3 * 7
24 --> 2 * 2 * 2 * 3
27 --> 3 * 3 * 3
Next, you find all the factors that they have in common.
They all have at least one 3, so that means that 3 is the greatest common factor of 21, 24, and 27.

Answer:
5y=9x-2
y=mx-b
m=slope
y=9/5x-2/5
m=9/5=1.8 slope of pArallel
slope of pARALLEL=-1/M SLOPE OF A LINE PERPENDICULAR
m=-5/9 slope of a line perpendiculr
