90 solve for x, with variables on both sides of equation. (note: x is the same thing as 1x) you must show your work 9x = x + 4

45

step-by-step explanation:

30+15

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
