Lines are parallel if they never intersect. To determine if two lines are parallel, you can follow these steps:
1. Check their slopes: Calculate the slope of each line using the formula (change in y)/(change in x). If the slopes are equal, the lines are parallel. If the slopes are different, the lines are not parallel.
2. Check their y-intercepts: If the lines have the same slope but different y-intercepts, they are parallel. If both the slope and the y-intercepts are equal, the lines are identical and not parallel.
3. Check their equations: If the equations of the lines are in the form y = mx + b, where m is the slope and b is the y-intercept, compare the slopes and y-intercepts. If the slopes are equal and the y-intercepts are different, the lines are parallel.
Remember, parallel lines never intersect, meaning they will maintain the same distance between each other in every point along their lengths.
