(0, 9) represents the y-intercept of the graph.
Since the slope is 1/3, this means that y will rise 1 for every 3 that x runs.
The points that can be used to make a line in this graph are (3, 10) and (6, 11).
The slope represents the how fast the bird is climbing and the Y intercept represents where the bird started to climb
I would estimate around 6 because say it was 6.5 and 3 then it would around the square root of like 31 and that is rounding down a lot so we would bump it up to somewhenre around 35 so the side would be around 5.8-6
The given system of equation that is
and
has infinite number of solutions.
Option -C.
<u>Solution:</u>
Need to determine number of solution given system of equation has.

Let us first bring the equation in standard form for comparison


To check how many solutions are there for system of equations
, we need to compare ratios of 
In our case,



As
, so given system of equations have infinite number of solutions.
Hence, we can conclude that system has infinite number of solutions.
