Hi andyboy179,
What you have there is the graph of a straight line.
is in slope-intercept form .
The y-intercept is 8. So graph (0, 8).
The slope is 2. So, from (0, 8) move up 2 units and right 1 unit to plot your second point at (1, 10).
Connect the two points with a straight line and extend the line past the two plotted points (the line is infintely long).
