The equation of the line CD is (y-3) = -2 (x-4). what is the scope of the line perpendicular to line CD

y=-1/2x-5

Step-by-step explanation:

First we need to put (y-3) = 2 (x-4) in slope intercept form.

we need to do order of operations ...

so we need to first do the parenthesis

x*2 = 2x

2*-4 = - 8

y-3=2x-8

add 3 on both sides to isolate y

y = 2x-5

so now we know the y=mx+b form

this is one line ...

now we need to find out what line is perpendicular.

Perpendicular lines have opposite reciprocals slopes.

y=-1/2x-5
