Answer:

graph{y=-x+3 [-3.666, 6.414, -0.817, 4.223]}

Explanation:

Equation is in Slope-Intercept Form #y=mx+b# where m is slope and b is y-intercept.

b=3, so y-intercept is 3.
The negative sign before the #x# indicates a slope of #-1# or #-1/1#, which means you will go down one unit and then right another to get your next point.

Now graph the y-intercept (0,3), and plot additional points using the slope as a template.
