Question

The lines shown below are parallel if the green line has a slope of 5 what is the slope of the red line

Answer 1

They both have a slope of 5 because they are parallel (if they did not have the same slope then that means they would touch at some point which makes them non-parallel lines)

Answer 2

If the lines are parallel that means they will never intersect to make sure that they never intersect two parallel lines always have the same slope
