1) 1-9(3 + 3x)

Consider the line y = -3/-2 x +6. find the equation of the line that is perpendicular to this line and passes through the point (-9,-3). find the equation of the line that is parallel to this line and passes through the point (-9,-3).

What is the solution to the equation 9^(x+1) =27

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?
