Please Help The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD? (4 points) A) 1 over 2 B) 2 C) negative 1 over 2 D) −2

A perpendicular line to line CD must have a slope of 1/2 (one half), which is  answer A in the list of possible options.

Step-by-step explanation:

If line CD responds to the following equation:

notice that this equation is given in slope-point form, telling us that the slope of this line is "-2", and one of the points on the plane the line goes through is (4, 3).

Now, a line perpendicular to CD must have a slope equal to "The opposite of the reciprocal" of the slope line CD has (-2). Then a line perpendicular to CD must have a slope equal to:

the discriminant is 64 + 4*1*12 = 112

this is prime.
