Which are equivalent expressions? Check all that are true.
2x + 6x + 12x = 2(x + 3x + 6x)
3x + 8y = 3(x + 2x)
7x + 6y = 42xy
9x + 2y = 2(4x + y)
11x + 22y = 11(x + 2y)

i believe the answer is c.

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

sorry i just need to anwers this to get points
