Hannah wants to rewrite 18+1218+12 using the greatest common factor and the distributive property. which expression should she write
a.6(3+2)
b.3(18+2)
c.6(18)+6(12)
d.6(3+12)

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
