Plug/Graph in y=7/9x+2
Explanation:
This is not in yintercept form, so we will need to that first.

To make things easier, subtract 18 from both sides,
You should now have: 7x9y = 18 
Now, try to get that y by itself. We can easily do this by subtracting 7x.
You should have: 9y = 7x 18
 We want to isolate the 9 from y, so divide 9 on both sides.
You would get: y= 7/9x +2
NOTE: You can graph this answer with your graphing calculator (y= button) and plot the points there, but if you don't have a graphing calculator, plug in various xvalues and solve the equation for your yvalue.
