How do you fnd the slope of a line parallel to the graph of each equation y=4x?

Jun 24, 2015

The slope of all lines parallel to $y = 4 x$ is $4$.
Any line in the form $y = m x + b$ is in slope-intercept form with a slope of $m$ and a y-intercept of $b$.
Writing $y = 4 x$ as $y = 4 x + 0$ lets us consider the equation to be in slope-intercept form
with a slope of $4$.
