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.
