Answer:
Two lines are parallel if their slopes are the same but y-intercepts are different.
Step-by-step explanation:
Two lines are parallel if their slopes are the same but y-intercepts are different.
Example:
y = 3x + 2
is a straight line with slope 3
Any line with slope 3 but y-intercept different from 2 is parallel to the given line.
y = 3x + 1
y = 3x -5
y = 3x + 1/6
are all parallel to the line.
