# How do you graph the line y = 3x + 1?

You have to find two points on the line, that is, two points that satisfy the equation $y = 3 x + 1$. But using the equation of the line if you take $x = 0$, you get $y = 1$, so the point $\left(0 , 1\right)$ is on the line. Similarly, you can take $x = 1$ and the equation gives you $y = 4$, so the point $\left(1 , 4\right)$ belongs to the line. Now you only need to mark these two points on a graph, and draw the line going through them, like so:
Of course, any other pair of points on the line would have been the same, such as $\left(2 , 7\right)$ and $\left(3 , 10\right)$ for example
