Question

How do you graph `y = x + 3`?

Answer 1

See below

Explanation:

The graph is already in the form `y=mx+b` where `m` is the slope and `b` is the y-intercept.

In this case, our y-intercept is `3` and our slope is the imaginary `1` that's in front of `x`.

So you make a point at `(0,3)`. Then, using the slope, we can see that adding `1` to `x` would do the same to `y` and subtracting `1` from `x` would subtract `1` to `y`. So a couple of other points would be `(1,4)`, `(2,5)`, and if we're going down, `(-1,2)`. Now we can just connect the dots:

graph{y=x+3 [-10, 10, -5, 5]}
