Problema Solution

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

Answer provided by our tutors

This is not an appropriate word problem but should be solved through algebraic tools from Algebrator. 

A perpendicular line is "-1" time the inverse of the slope.  The denominator of the slope must be non-zero. 

The equation "(y−3) = − 2 (x − 4)" is graphed in order to place the equation in the standard linear form.
