Question 321322: Identify which equation is a graph of a vertical line.
x = 4y
y = 4
x = 4
4x = y
is the answer; y=4?
Identify which equation is a graph of a horizontal line.
2x + 3 = 4y
–4x = 8
2x = 3y
2y = 10
is the answer; 2x=3y?

Hint: ALL vertical lines are of the form x=k where 'k' is some constant number. Ex: x=2 and x=12 are vertical lines. On the other hand, ALL horizontal lines are of the form y=k where 'k' is some constant number. Ex: y=8 and y=22 are horizontal lines.
