You can put this solution on YOUR website! I assume you mean a slope of 1/3.
First plot your point (-2,-4).
The slope is change in y over change in x.
You line will increase 1 y increment for each 3 x increments.
Starting at (-2,-4), another point would be
x:-2+3=1
y:-4+1=-3
(1,-3)
Plot that one.
You could keep going but for a straight line you only need two points.
Draw the line between those two points.
You can also find the equation of the line using the point-slope form.
