Question

Identify which lines are parallel.
y=2;y=x+2;y=2x-1;y=2x+1

Answer 1

y=2

Explanation:

A parallel line are lines that never intersect.

-They are generally formed when a line when lines are perfectly horizontal to the x axis or the vertical to the y-axis.

=>y=2 is the only parallel line .

=>y=x+2 is not parallel as the (x+2) is not a constant

=>y=2x-1 is not parallel as the (2x-1) is not a constant

=>y=2x+1 is not parallel as the (2x+1) is not a constant
