graph{-x+4 [-16.02, 16.02, -8.01, 8.01]}

Explanation:

In your equation (y=−x+4), −x, or −1x, is your slope and +4 is your y-intercept.

To graph this, start by plotting your y-intercept on your y-axis (remember, your y-intercept is +4).

Then, since your slope is negative, your line will be going down (high-left to low-right). From the dot you just made on your y-axis, go to the right once (one box), and down once (one box), since your slope is −1x, and the formula for slope is riserun. Continue this pattern, and extend your line.

Your slope should look similar to the graph above :)
