Question

Write the equation of a line parallel to the line y = 3, that passes through the point (1, 6).

Answer 1

y = 3 has no slope

Answer 2

parallel lines have the same slope
so m=0 and you know (1, 6)

y-y1=m(x-x1)

where
(x1,y1) is the point given to you

Answer 3

m=slop

Answer 4

plug in all the information

Answer 5

It's a horizontal line, and you want another horizontal line. Look at the y value from (1,6) and that is what your horizontal line will be at.
