Identify which lines are parallel. y=2;y=x+2;y=2x-1;y=2x+1
1 answer:
Answer:
y=2
Step-by-step 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
