Explanation below.

This is a line with slope $2$ and $y$ -intercept $6$ .

Since a straight line can be defined with as few as two points, you can do the following:

Plot the point $(0, 6)$ first, since the point where the line intercepts the $y$ axis has $x = 0$ .

Then, pick any value other than $0$ for $x$ , find the corresponding $y$ value, then plot that point as well. For example,

for $x=1$ , $y=2 + 6 = 8$ . So the point is $(1, 8)$

Connect both points, and extend the line in both directions.
