First you have to change "-2x+6y-9=0" into slope intercept form (y=mx+b).
Add the -9 to 0, to get (-2x+6y=9).
Now add -2x to the 9, to get (6y= -2x+9). Since -2x and 9 aren't like terms.
Divide 6 on both sides to get (y=-2/6x+9).
Plot this on a graph as shown above. (16.5, 3.5)
Answer is: D) 3.35, since it's closer.
