A. Is your answer, if the games cost the same amount and he bought 3, that would give you 3x, the total is 65, and 14 is what was left. You would subtract 14 from the total, then divide by 3 to get x by itself.

Step-by-step explanation:
The equation of a line is
, where
is the slope and
is the
intercept.
We know that the line pass through the point (1,1) and the slope is 2.

Then,

We have to find
.
If we replace the point (1,1) in
we will obtain
.
Then,


The y intercept then is -1, this means that when x=0, y=-1.
We have the point (0,-1).
Now to obtain another point we have to replace
with y=0.

We have the point 
Now that we have to points, we have to place them in the cartesian coordinate system. And then draw the line.
