Question

How do you graph `y + 2 = 7`?

Answer 1

Given equation is `y+2=7`. It seems that we can simplify it further by taking the 2 to the right hand side. So we get `y=7-2=5\impliesy=5`

Notice there's no `x` parameter in the given equation, so it doesn't matter what value of `x` you take, may it be `4` or `6`, the answer is the same, it's `y=5`

So do just that, take a point `(0,5)`, then take any graph{y+0x=5 [-9.71, 10.29, -1.72, 8.28]} other point where the `y` ordinate is `5`, that's the graph of the function.

You'll also notice that the given line will be parallel to the x-axis and also learn that the equation of a line of the x-axis can be written as `y=0`.
