How do you find the slope of a line parallel to graph of this equation y=4x+2?
slope = 4
We have to know that
#color(blue)"parallel lines have equal slopes"#
The equation of a line in
where m represents the slope and b, the y-intercept.
The advantage to having the equation in this form is that m and b, may be extracted 'easily'.
The equation here y = 4x +2 is in this form.
and by comparison with the slope-intercept form.
slope = 4 and so slope of parallel line is also 4.
