# How do you graph y= x + 3?

To draw the graph of the equation $y = x + 3$, one needs to find at least three sets of $\left(x , y\right)$ (as this is a linear equation and hence represents a straight line) which satisfy this equation. (Although two should be alright, three are preferable as any set of wrong numbers will show up.)
Let us take wide spread values of $x$m say $- 8$, $0$ and $8$. Putting these in the equation $y = x + 3$, we get $y$ as $- 5$, $3$ and $11$ respectively.
Hence, three sets of $\left(x , y\right)$ are $\left(- 8 , - 5\right)$, $\left(0 , 3\right)$ and $\left(8 , 11\right)$. Now draw these points and join them to form a straight line.
