2(x + y) + 9x +6y
Please answer!

11x + 8y

Explanation:

2(x+y)+9x+6y

Distribute:

=(2)(x)+(2)(y)+9x+6y

=2x+2y+9x+6y

Combine Like Terms:

=2x+2y+9x+6y

=(2x+9x)+(2y+6y)

=11x+8y

=11x+8y

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
