Find the slope of every line that is parallel to
the graph of the equation.
y - 4x = 1

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 :))
