Answer:
See attached file
Explanation:
We want to graph the equation

We can plot two points and draw a straight line through them.
The easiest points to plot are the intercepts.
When x=0, y=2*0+6=0+6=6
So we plot our first point (0,6)
When y=0, we have 0=2x+6


We again plot (-3,0)
With a straight edge we draw a straight line through the two points to obtain the graph in the attachment.
