What is the GCF of 27 andd 63?

9

Step-by-step explanation:

Greatest common factor (GCF) of 27 and 63 is 9.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the height of the surface increases from the center out to the sides of the road

it is c!
