Explanation:
Parallel lines have the same slope.
Get the slope using the points passed through by the first line
Get the equation of the second line
Substitute the point passed through by the second line to get the y-intercept
Hence, the equation of the second line is
To determine another point that the line passes through, simply select a desired value for either
For simplicity, let's use
Hence, we have
