Which equations have the same value of x as 5/6x+2/3=-9

Select three options

a.18x-15=72

b.50x-25=72

c. 18x-9=72

d.3(6x-3)=72

e. x=4.5

b is the final answer! : )

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
