B.)Y=+%281%2F4%29x%2B2......slope is m=1%2F4...y-intercept is (0,2)

check:
use a slope and y-intercept to find equation of a line
m=-5 and (0,4)
Solved by pluggable solver: Find the equation of the line(with graph)---slope a nd y-intercept:given

Using the slope-intercept form,
y=mx%2Bb
where m=slope, b=y-intercept,
and, substituting the values m=-5 and b=4,
y=%28-5%29x%2B4
And the general equation is,
%28-5%29x-y%2B4=0
