Write an equation of the line that passes through the given point, (1, 2).

Step-by-step explanation:

eq. of any line through (1,2) with slope m is

y-2=m(x-1)

if the line is parallel to x-axis then y=2

if the line is parallel to y-axis then x=1

the first and second pictures are answer of √5c^6 d^5

the third and fourth pictures are answer of √20c^6 d^5

I hope this helps a little bit .
