Answer explanation

Once we identify the new slope we can use the new point (given to us) and the new slope (we found) to use point-slope form and solve into slope-intercept form.

The lines have to be parallel so the slopes must stay the same!

Answer explanation

Once we identify the new slope we can use the new point (given to us) and the new slope (we found) to use point-slope form and solve into slope-intercept form.

The lines have to be perpendicular so the slopes must be opposite reciprocals.

m = 4 becomes m = -1/4
