Step 1. I assume you want to plot this line using the slope-intercept form.
Step 2. The slope-intercept form is given as y=-mx+b where m is the slope and b is the y-intercept at b or at point (0,b).
So the equation is y=-2x+0=-2x or
Step 3. Here's a plot of the line and note the slope m=-2 and b=0. Note that a slope m=-2 means one unit to the right is two units down.
I hope the above steps were helpful.
