Two lines that are parallel have the same slope. So, the question is, what s the slope of y = 5x -1? This equation is in slope-intercept form (also known as y = mx + b) and the coefficient in front of the x (also known as "m") is the slope. So this line has a slope of 5. The line parallel to it, also has the slope of 5.
