To find another point, use the slope.
Slope is change in y over change in x.
So for each {{{1}}} change in {{{x}}}, there is a {{{4}}} unit change in {{{y}}} since {{{m=(DELTA*y)/(DELTA*x)=4/1=4}}}
Start at the intercept to find another point.
x:{{{0+1=1}}}
y:{{{-4+4=0}}}
(1,0) is another point on the line. 
Plot it and connect the two points with a line.
