slope = 4
Explanation:
We have to know that
#color(blue)"parallel lines have equal slopes"# The equation of a line in
#color(blue)"slope-intercept form"# is
#color(red)(|bar(ul(color(white)(a/a)color(black)(y=mx+b)color(white)(a/a)|)))#
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.
