What is the slope of a line parallel to #y=3x+5#?
A line parallel to this one would have a slope of 3.
When trying to figure out the slope of a line it's a good idea to put the equation into "slope-intercept" form, which:
where m is the slope and b is the y intercept.
In this case, the equation
Parellel lines have the same slope, so any other line with slope 3 is parallel to this line.
In the graph below, the red line is
