Question

How to do you graph `y=-x +4` by plotting points?

Answer 1

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 `"rise"/"run"`. Continue this pattern, and extend your line.

Your slope should look similar to the graph above :)
