Six times the sum of a number and 3 is equal to 5. use the variable b for the unknown number.

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

27 +27 or 27times 2=54

the diffrence is 0
