The slope of every line parallel to this line is -4.
Why is it -4, you may ask? Well, you first have to recall the slope-intercept format, which is y = mx + b.
In the slope equation y = mx + b, 'm' represents the slope and 'b' represents the y-intercept.
Now recall that if a line is parallel to another line, they share the same slope.
What is the 'm' for the line equation we've been given, y -4x = 1? It would be -4.
Good luck! If you have any questions, just ask :))
