Answer:

y=2x-6

Step-by-step explanation:

First find the equation of line AB

y=mx+b

m = slope

b = y- intercept = -1

m=rise/run

m=-1/2

y=-1/2x-1

if AB is perpendicular to CD, then slope of CD is inverse reciprocal = 2

then use the following to find equation of CD, using coordinates ( 2,-2) as (x1, y1)

y-y1=m(x-x1)

y- (-2)=2(x-2)

y+2=2x-4

y=2x-6
