slope = 4


We have to know that #color(blue)"parallel lines have equal slopes"#

The equation of a line in #color(blue)"slope-intercept form"# is

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.
