What is the equation of the line perpendicular to y=1/2 x+3 passing through the point (-3,4)

Solve for x i'll try to attach the files bc it's not letting me for some reason

Find the solution set of this inequality. select the correct graph. |8x+16|> 16

Which of the following is the correct equation for this function? a. y= (x+4)(x+2) b. y=x^2+ 3x – 2 c. y+ 2 = – 2(x+3)^2 d. y+ 2 = 2(x+3)^2
