Question

Draw a line CD perpendicular to AB which intersects at point B. ​

Answer 1

y=2x-6

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

Answer 2

See attached

Explanation:

Since the slope of line AD is -1/2, then the slope of our perpendicular line should be positive 2.
