How do you graph y=x+3?

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]}
