Question

The equation of line CD is (y-3) = - 2 (x - 4). What is the slope of a line perpendicular to line CD?

Answer 1

My choices are
A) 2
B) 1/2
C) -2
D) -1/2

Answer 2

I believe the answer is -2.

Answer 3

Because I found the equation y =1/2x perpendicular to equation CD but I don't understand what the slope would be would it be 1/2?

Answer 4

I think its either 1/2 or -2 but not sure which one of the two.
